This document is the principle (and almost complete) reference for understanding the operation of the AEA CPU per se, the AEA assembly language and assembler, and the operation of the CPU's i/o ports. There are, however, some confusing aspects to the document:66-542-01 A, "Gemini Programming Manual", 05/24/1966, by C. A. Leist, J. C. Condell. Written by original Gemini programmers Charlie Leist and Jim Condell, and describes programming the on-board computer from the programmers' perspectives; as such, it discusses various pragmatic difficulties rather than just the theoretical ideal, though it also covers the on-board computer's CPU instruction set and similar topics in a way that both overlaps and differs from the "Guidance and Control Systems" documents listed in the item above. Charlie has additionally (in 2011) thoughtfully recreated a missing document page for us.AGC4 MEMO #9, Rev 1, "Block II Instructions" or here, 07/01/1966, by Hugh Blair-Smith. This is the source for info on AGC assembly language. Incidentally, I've taken to calling this the "infamous memo", simply because I think it's funny, but I notice that this phrase is being used occasionally on the web. I don't actually know that there's anything infamous about it, so if you plan to quote me, you might want to leave out the word "infamous".E-2052, "AGC4 Basic Training Manual" or here, volume I of II, 01/1967, by Bernard I.

Unfortunately, this set of reference cards is missing the front cover and seemingly other pages.

I haven't tried doing that, as of yet.Anonymous. Alas! most of us don't have one of those.Anonymous. A one-side-of-one-page reference to all Block II AGC instructions.MIT Instrumentation Laboratory.

AC Electronics. This is pretty preliminary. It's interesting — your opinion may vary — that it appears to be based on SUNRISE 69 AGC software, as opposed to the SUNSPOT (247?) software that would have flown in Apollo 1. To the best of my present understanding, CORONA was forked from SUNRISE 69, and SUNSPOT was eventually branched from CORONA 261. Thus over 500 software revisions of CORONA and SUNSPOT existed between the one on which these reference cards are based and the one which would have flown. Preliminary indeed!AC Electronics. O. Oh. Cerbins. The cover (if any) is missing, so the title is one we invented after the fact. The thing that interests me most is that for some reason the final card is a proposed list of Apollo missions, none of which had as-yet occurred.

Stokes, Jr.If you're really paying close, close attention, you may wonder why all of our information on the COLOSSUS page and this page indicates that the same software was used for the Apollo 15-17 CM, namely ARTEMIS 72, and yet the linked document indicates ARTEMIS 72(REV1) instead. Conversely, the Apollo 15 document linked above indicates merely ARTEMIS 72 without a revision. Sounds different, doesn't it? Well, we don't presently have enough information to resolve this puzzling paradox with satisfying certainty. However, Nik Beug points out that the Operational Data Book actually does list ARTEMIS 72 REV 1 for Apollo 16 as well, while Mike Stewart points out that the AGC's memory modules have the same manufacturing dash numbers for Apollo 15 and 16 (indicating that they had the same software loads stored in them). This lends a lot of credence to the notion that all three of these missions really did have the same software load. Plus, you have other support, such as memos like this one. But whether that software version was ARTEMIS 72 or whether it was ARTEMIS 72 REV 1 is still unclear, and the available data allows it to be argued either way.FS66-72-162, "Final LM Guidance Computer (LGC) Prelaunch Erasable Load for Apollo 17", 12/04/1972, by James C.

If just seeing
what went into each mission isn't enough for you, and you need to see the vast
sweep of all the AGC and AGS software development from the beginning in 1963
until the end in 1971, I have a chart of that as well. Alas, there's no LVDC
info in the chart, and I've had to leave out some AGC non-mission branches like LA MESH,
DIANA, and so forth. But I included some non-mission branches,
particularly SHEPATIN and ZERLINA, since we actually have representative
copies of those. There's a small detail
from the full chart to the right, and if you click that image, the full chart
will appear. Admittedly, there's some guesswork involved because of lacking
information, particularly in the very early years, but I think the chart
captures pretty well what's going on. Each bubble in the chart represents
some specific revision of some specific AGC program, or else a range of
revisions when there's just too much information missing to distinguish
between them. Gray bubbles are Block 1 code, brown bubbles are Block 2 CM
code, yellow bubbles are LM code, and white bubble are AGS. The name of the
AGC program is in red if
core ropes were actually manufactured for that revision. The arrows connecting
the bubbles tell you what revisions of what programs evolved into what other
revisions. The arrows are also decorated with lists telling what PCRs, PCNs,
software-anomaly reports, and ACB requests were involved in that particular
stage of the evolution — though in many cases that's simply "TBD", as it
actually is in the detail image at the right. The
full chart, by the way, is about 40 times as high as it is wide, so be
prepared to scroll downward a lot if you look at very much of it.| Assembly # | Software Name | Software Revision | Usage | Release Date | Reference(s) |

Hugh Blair-Smith. Hugh Blair-Smith. TRIVIUM is a sample AGC program presented in a document called "YUL Programming System", as an example of how to write and assemble an AGC program using the YUL assembler. It is the earliest AGC program presently known to us, though as its name implies, it is trival in nature. (Though knowing Hugh, he may have meant it had something to do with grammar, logic, and rhetoric ... which to a certain extent it does.) As short as the program is, it has several intentional errors in it, in order to illustrate YUL's errors and warnings.See also:

The Programmable Test Controller (PTC) is laboratory-based test equipment (LTE) associated with the LVDC. In fact, it contains a modified LVDC, for which the PTC ADAPT Self-Test Program is the software. In other words, this software is essentially an LVDC program, though with some small differences. The syntax is very slightly different from that of a standard LVDC program. The principal distinction we are aware of right now is that multiplication and division instructions are replaced by i/o instructions; i.e., multiplications and divisions are performed by some peripheral device rather than by the CPU itself. Because it is not guidance software — it is a self-test program — there is no reason to suppose that there is any restriction for its "export" under ITAR; thus, it is presented in full here. In any case, it's freely available elsewhere online, without restrictions. Comparatively, the source-code portion of the listing is 170 pages, whereas an LVDC flight program has around 300 source-code pages, so while the PTC ADAPT Self-Test Program is smaller than an LVDC Flight Program, it is not trivial in comparison either. It's worth noting that the software listing is found in Chapter 7 of the PTC manual, but that preceding it in the manual, you can also find the user instructions for running the program.See also:

RETREAD 44 (p/n 2021100-011) was released for manufacturing of memory modules containing it in July 1965, but those memory modules never flew any missions.

AURORA 88 is an AGC program that was standard for check/acceptance of LM guidance-system assembles. The present source code was reconstructed, using other known AGC source code as a resource. It assembles identically to octal data dumped from physical AURORA 88 core-rope memory modules.See also:
MIT Instrumentation Laboratory. AURORA was the successor to RETREAD, and like RETREAD it never flew any missions. We have three records of AURORA being manufactured as memory modules, but those seem to reduce to only two actual releases: AURORA 85 (p/n 2021101-011) in March 1966 and AURORA 88 (p/n 2021101-021) in July 1966. Unfortunately, this doesn't seem to correlate too well with our own printout of AURORA, which according to the printout is REVISION 12 OF PROGRAM AURORA BY DAP GROUP, with the assembly having been run on November 10, 1966. Why was an assembly of AURORA 12 being made in November 1966, when AURORA 88 had already been released in July? The answer is that AURORA 12 was not being assembled or printed in November 1966, but that our assembly listing is instead that of a program (which I call "DAP AURORA"), which was forked by the Digital Autopilot (DAP) Group from the true AURORA at either AURORA 86 or AURORA 87. After being forked, the DAP Group apparently used it for developing the SUNBURST program, and there's a lot of buggy SUNBURST code appended to the end. (By which I mean, past the last of the memory sectors used by true AURORA.) In other words, what we have here is indeed revision 12, but it is revision 12 of DAP AURORA rather than revision 12 of true AURORA. See also:
1021108-021, "Assembly Listing of AGC Program SOLARIUM 55", 12/04/1966, by MIT Instrumentation Laboratory. SOLARIUM 55 flew as the CM AGC software on the unmanned Apollo 4 and Apollo 6 missions. In theory, SOLARIUM 54 is the software which officially flew on the unmanned Apollo 4 mission, but it's difficult to escape the conclusion that SOLARIUM 54 and 55 were identical even though given differing revision numbers for some reason. The Apollo 4 and 6 Command Modules were Block 1 spacecraft, and hence unlike almost all other AGC programs in our library, SOLARIUM is a Block 1 AGC program.See also:
MIT Instrumentation Laboratory. SUNBURST, a successor to AURORA, was the first AGC LM software to fly in a mission ... albeit, not this specific revision of SUNBURST.See also:
2021104-041, 2021104-051, "Assembly Listing of AGC Program SUNDIAL E", 03/13/1967, by MIT Instrumentation Laboratory. SUNDIAL E is a Block II AGC program that was "flown" the series of missions known as 2TV-1. These missions were crewed, but took place on the ground, and were used for thermal/vacuum testing of the CSM. Additionally, SUNDIAL E was used for acceptance testing of G&N systems. The present source code was reconstructed, using other known AGC source code as a resource. It assembles identically to octal data dumped from physical SUNDIAL E core-rope memory modules.See also:
2021104-031, 2021104-041, 2021104-051, 2021104-061, "Core dump of AGC Program SUNDIAL E", 03/13/1967, by MIT Instrumentation Laboratory. SUNDIAL E was Block II CM AGC software never intended for flight. Rather, it was used for ground-based checkout of the CM G&N system, using elaborately-devised procedures. It was apparently the software used for the 2TV-1 (Block II Thermal Vacuum no. 1) CM AGC, and in that sense "flew" 4 missions, even though it never left the ground. We unfortunately do not have a contemporary listing of SUNDIAL E source code. Nor do we presently have reconstructed source code for it. What we do have is a core dump of the physical memory modules from an AGC owned by the MIT Museum. This core dump can be disassembled into user-unfriendly AGC source code — i.e., source code without embedded remarks, in which arbitrary labels are used instead of meaningful variable names and subroutine name — but we are not presently providing such a disassembly. Hopefully, we will eventually have a human-friendly reconstruction of the disassembled source code, but so far that has proven to be a challenge which hasn't been addresssed. Of course, with the core dump, SUNDIAL E can still be run our AGC CPU emulator (yaAGC); no source code needed for that!See also:

Dump of physical B3 rope-memory module for SUNDIAL E.IBM Federal Systems Division. While I have the scans and transcribed source code for this program, there may be legal difficulties in providing them online. Specifically, there are U.S. regulations known as ITAR, which may make it illegal to "export" this program, or more specifically, to provide it to anyone who is not a "United States person". I have been attempting through legal means for some time now to determine if there is any way for me to provide it online. At present, if you want the program and if you can supply credible evidence that you are indeed a "United States person" (look it up!), contact the email address given at the bottom of this page, and I'll see what I can do for you.2021106-031, "Assembly Listing of AGC Program SUNBURST 120", 12/07/1967, by MIT Instrumentation Laboratory.

Hugh Blair-Smith. This is the Honeywell H-800 source code of the original YUL assembler for AGC code. It was superseded by the GAP assembler, for which we have no source code. While YUL's source code is for the H-800 computer, it is not written in the H-800's assembly language, ARGUS, but is instead written in something called MITIGUS. We don't have an exact description of MITIGUS, nor the preprocessor software that converts MITIGUS to ARGUS ... which we'd have no way to run anyway.

In fact, we can't even say that it's LM software or CM software, but merely that it is AGC software. And it wasn't even written by the MIT Instrumentation Laboratory, but actually by Raytheon (the manufacturer of the AGC) instead. It was part of a test of an "auxiliary memory" system for the AGC. The auxiliary memory was a magnetic tape drive, from which programs could be loaded into the AGC in flight. Apparently the auxiliary memory worked, but it never ended up being used.See also:

What we do have is a set of dumps of core-memory modules, of various revisions of SUNDANCE, from various people's private collections, and an attempt by Mike Stewart to use this hodge-podge of material to recreate SUNDANCE 306 from them. Of the 6 core-rope modules, we actually have 7 dumps:See also:

2021112-011, "Assembly Listing of AGC Program LUMINARY 69", 11/25/1968, by MIT Instrumentation Laboratory. This seems to have been the first LUMINARY revision targeted at the Apollo 10 mission, and seems additionally to have been the first revision of LUMINARY for which core-rope modules were manufactured. In other words, it was the first non-developmental revision of LUMINARY and the first released for manufacturing. Nevertheless, it ended up not being flown in the mission. For that, see LUMINARY 69 Rev 2.See also:
2021112-031, "Assembly Listing of AGC Program LUMINARY 69 Rev 2", 01/30/1969, by MIT Instrumentation Laboratory. LUMINARY 69 Rev 2 was flown in the Apollo 10 LM AGC. We do not have any actual contemporary listings of the source code. But the software has been reconstructed with almost-perfect confidence by Mike Stewart. That was possible because the following elements were all present:See also:
2021113-011, "Assembly Listing of AGC Program COMANCHE 44", 02/1969, by MIT Instrumentation Laboratory. This is the first software release of COMANCHE targeted for Apollo 10 whose rope-memory modules were manufactured, but it was superseded and did not fly. We have no contemporary source-code listing for it at present, although a listing is known to have survived. The source code has, however, been reconstructed by Mike Stewart, with the expectation of 100% accuracy. The reconstruction began with known-good source code from the closely-related COMANCHE 51; in response to documentation about the changes between COMANCHE 44 and 51 found in various PCRs, PCNs, and Software Anomaly Reports, older code related to those changes was pulled in from the known-good COLOSSUS 249 source code. The end result was verified by the fact that its memory-bank checksums matched those for COMANCHE 44 listed in engineering drawing 2021153. Comments were also added to our transcription of the source code, for each of the differences between COMANCHE 44 and 51, so if you're interested you can view the changes in context by looking at either our code transcription or our colorized assembly listing. Mike also provided a detailed description of what he did, as he did it.See also:
2021113-021, "Assembly Listing of AGC Program COMANCHE 45", 03/1969, by MIT Instrumentation Laboratory. This is the second software release of COMANCHE targeted for Apollo 10, but it was superseded and did not fly. We have no contemporary software listing for it. Mike Stewart has reconstructed the source codee, however, with what we think is 100% fidelity. The reconstruction process is essentially the same as described in the comment for COMANCHE 44, except that it started wtih COMANCHE 44 and COMANCHE 51 as baselines and was overall easier to accomplish, so I'll just direct you the COMANCHE 44 comment to get a general idea of how the reconstruction process worked.See also:
2021113-031, "Assembly Listing of AGC Program COMANCHE 51", 03/1969, by MIT Instrumentation Laboratory. Comanche 51 was the software release initially intended to be used in the Apollo 11 Command Module. Its rope-memory modules were manufactured, but it was superseded and never flew. We do not have a contemporary listing of the source code, but it has been reconstructed with, we believe, 100% confidence. Mike Stewart has written up an explanation of the reconstruction process. In brief: We had the known-good source code for Comanche 55, and we knew that the difference between Comanche 51 and 55 was the addition of the so-called R-2 lunar potential model. Therefore, if the code for the R-2 lunar potential model were removed from the source code for Comanche 55, we should have the source code for Comanche 51. The R-2 model had also been added to LUMINARY, so the implementation details of how that related to the actual source code were relatively clear. Having made these changes, engineering drawing 2021153 contains a list of memory-bank checksums for the COMANCHE rope modules which had been manufactured, including the checksums for COMANCHE 51. The checksums do agree.See also:
2021113-041, "Assembly Listing of AGC Program COMANCHE 45 Rev 2 (or MANCHE 45 Rev 2)", 04/1969, by MIT Instrumentation Laboratory. This flew as the CM AGC software on Apollo 10. We have no contemporary software listing for it. Mike Stewart has reconstructed the source code, however, with what we think is 100% fidelity. The reconstruction process is essentially the same as described in the comment for COMANCHE 44, except that it started wtih COMANCHE 45 and COMANCHE 51 as baselines and was overall easier to accomplish, so I'll just direct you the COMANCHE 44 comment to get a general idea of how the reconstruction process worked. Interestingly, there is an additional accuracy confirmation (beyond just matching of memory bank checksums in engineering drawing 2021153) which we don't have in most of the AGC software reconstructions. Months after reconstruction had completed, a contemporary user manual for the GAP program (the contemporary assembler used) turned up. In an Appendix at the back was a complete core dump of one of the COMANCHE 45 Rev 2 memory banks, as well as partial dumps of two other memory banks, and a complete list of differences between the core dumps of COMANCHE 45 vs 45 Rev 2. In all cases, the data in the GAP manual's Appendix matches the actual reconstruction.See also:

MIT Instrumentation Laboratory. ZERLINA is a branch of main LUMINARY source code, which could be treated as a workbench for trying out ideas without fear of affecting LUMINARY. Ideas which proved valuable could then be ported back from ZERLINA into LUMINARY. The largest such idea that I'm aware of that was treated in this way was the "variable servicer", which reduced CPU usage by omitting certain guidance computations when they weren't really needed, as opposed to inflexibly recomputing them at fixed intervals. By thus keeping the CPU usage at an overall lower percentage during lunar descent, the probability of overloads causing 1201/1202 alarms such as those in the Apollo 11 landing would be greatly reduced. (Yes, I know that the 1201/1202-alarm overloads were caused by the Rendezvous Radar being unexpectedly active, from the AGC's point of view. But with the variable servicer, the CPU load would likely have been low enough that it probably wouldn't even have mattered if the RR was active or not.) Unfortunately, while (I think) that the variable servicer was regarded as a good technical solution, it was then late enough in Project Apollo that it was regarded as safer and possibly cheaper to avoid such drastic changes, and the idea of the variable servicer was eventually dropped.See also:
TRW. This was flown in Apollo 15, 16, and 17. Bibliographical references in other AGS documents mention TRW document 17618-H088-RO-00, "LM AGS Programmed Equations Document, Flight Program 8". In analogy to Flight Program 6, we would expect that the assembly listing of FP8 is actually an Appendix to the document just mentioned ... but at this point, that's purely speculation on my part.See also:

May be a description of the PCR rather than a title.PCR-?, "Attitude Command During Manually-Controlled Lunar Landing", 12/03/1969, by R. F. Stengel. Our copy of this PCR does not have a PCR number on it, nor indicate any disposition. On the other hand, PCR-885, rejected by the SCB, had the very similar title "Attitude command during manual landings". But it does not seem as though this PCR should be identified with PCR-885, because this PCR is dated 12/03/1969, whereas the SCB rejected PCR-885 on 10/09/1969. Moreover, a 12/02/1969 memo by this PCR's author is attached to the PCR, and it discusses the prior rejection of PCR-885. The memo, however, mentions neither this PCR, nor gives any reasons why this PCR would be more acceptable to the SCB than PCR-885 had been. Possibly this is a revision of PCR-885.PCR-?, "Eliminate P63 Alignment Option", 08/17/1970, by Don Eyles. Our copy of this PCR has no PCR number on it. I suspect that the PCR was never made official, because of the existence of the 09/23/1970 equivalent PCR-335, "Remove Alignment Option from P63" by Haise & Kaiser.PCR-?, "Simpler LR turn-on logic", 08/24/1970, by Don Eyles.

I've found 2 very different titles for this PCR, and can't tell if they represent the same thing or not, or whether this really two separate PCRs inadvertantly assigned the same number. And unfortunately, we don't have any pure-LUMINARY code earlier than the revision at which this PCR is applied, so that I could check to see if the deleted code might match both titles. Nor does the predecessor program, SUNDANCE, have a similar P11 ... because why would it, since it was used only for Earth-orbital operation? At any rate, I've simply concatenated the two titles, delimiting them with a semicolon.PCN-108, "P-37 Description Modification" (not dated).

SOLARIUM 55 flew as the CM AGC software on the unmanned Apollo 4 and Apollo 6 missions. In theory, SOLARIUM 54 is the software which officially flew on the unmanned Apollo 4 mission, but it's difficult to escape the conclusion that SOLARIUM 54 and 55 were identical even though given differing revision numbers for some reason. The Apollo 4 and 6 Command Modules were Block 1 spacecraft, and hence unlike almost all other AGC programs in our library, SOLARIUM is a Block 1 AGC program.See also:

Of the two scans, the primary one is much shorter, primarily because large sheets spanning multiple frames in the secondary scan comprise single pages in the primary scan. However, the scans appear to have been made from different physical hardcopies, and do differ in other ways in terms of readability and inclusions. This is just a fragment of the full document, and the metadata I've provided (date, title, revision, document number) is speculative. While it does have accompanying metadata, as well as a link providing additional metadata to the archive from which it came, that metadata isn't fully correct, thus forcing some guessed corrections from me. But from the page markings, it is clear that it relates to Apollo 1 (Spacecraft 012) and to the Apollo Operations Handbook. The date I've listed, 1/27/1967, comes directly from the page markings, and coincidentally was the exact day of the fire that destroyed the spacecraft.

The document is actually undated, though there are stamps and signatures on it from 1970. From the visual aging of the document, however, it's unlikely (in my not-so-humble opinion) to have been created in 1970. The document number, 65ICD9304, may indicate that it was created in 1965. As for the stamps and signatures from 1970, I'd note that missions AS-206 through AS-210 were originally scheduled for 1967 or thereabouts, but were canceled after the Apollo 1 disaster. The launch vehicles were eventually repurposed for Skylab and ASTP missions, for which some preparations apparently began in 1970. I would therefore theorize that this preliminary document was revived in 1970 as part of the early preparations for Skylab missions, and that that's where the references to 1970 in it came from.CR-124279(?), "Laboratory Maintenance Instructions: Saturn V Launch Vehicle Digital Computer, Simplex Models", volume I of II, 01/04/1965, by IBM Federal Systems Division. While the title of this document is undoubtedly correct from the standpoint of IBM Federal Systems Division (the corporate author), the document is more usefully viewed as a complete explanation of the theory of operation of the LVDC, albeit of a very early breadboard version.

The Programmable Test Controller (PTC) is laboratory-based test equipment (LTE) associated with the LVDC. In fact, it contains a modified LVDC, for which the PTC ADAPT Self-Test Program is the software. In other words, this software is essentially an LVDC program, though with some small differences. The syntax is very slightly different from that of a standard LVDC program. The principal distinction we are aware of right now is that multiplication and division instructions are replaced by i/o instructions; i.e., multiplications and divisions are performed by some peripheral device rather than by the CPU itself. Because it is not guidance software — it is a self-test program — there is no reason to suppose that there is any restriction for its "export" under ITAR; thus, it is presented in full here. In any case, it's freely available elsewhere online, without restrictions. Comparatively, the source-code portion of the listing is 170 pages, whereas an LVDC flight program has around 300 source-code pages, so while the PTC ADAPT Self-Test Program is smaller than an LVDC Flight Program, it is not trivial in comparison either. It's worth noting that the software listing is found in Chapter 7 of the PTC manual, but that preceding it in the manual, you can also find the user instructions for running the program.See also:

Chapter 11 is particularly relevant to the LVDC, as it discusses the flight software in some detail. Sadly, it does not show any actual sample snippets of LVDC software. You'll notice that we have three different revisions of this document. This earliest revision simply says that chapter 11 is "to be supplied later". One especially-important difference between the later two revisions, other than the fact that the final version has more-legible foldouts and is a much larger download, is that the aforementioned Chapter 11 has been completely rewritten between the 2nd and 3rd revisions: while the earlier version describes the LVDC software used in Apollo 11, the later version describes a new "generalized" LVDC program as used in Apollo 12. Another Apollo 12 vs 11 change is that the flight-sequence table (Chapter 4) differs.R-ASTR-NG-107-65, "Mission Defining Document for the AS-501 Launch Vehicle Digital Computer (LVDC)", 10/21/1965, by S.

While the launch-vehicle operational trajectory documents (as opposed to the spacecraft trajectory documents) do generally include tables of LVDC presettings, this is the only one I'm presently aware of that chooses to tell us the numerical addresses at which the (named) variables being preset actually reside.71W-00141, "Saturn Preflight Program Verification Plan", 05/01/1971, by IBM Federal Systems Division. 71W-00374, "Saturn Preflight Program Verification Plan", 12/10/1971, by IBM Federal Systems Division. 72-0005, CR-123571, "Flight Program Language Requirements", volume I of III, 03/07/1972, by T. T. Schansman, R. E. Thurber, L. C. Keller, W. M. Rogers. The 3 volumes of this document comprise a study that explores using alternate, higher-level programming languages in place of LVDC assembly language. The languages are SPL (Space Programming Language), CLASP (Computer Language for Aerospace Programming), HAL (High-order Assembly Language), and CMS-2 (Compiler Monitor System-2). Of these, HAL looks the most like a modern program language, naïvely speaking, though the report notes that it was the most difficult in which to program. Amusingly also, the language (in spite of its acronym-style name) was actually named by Ed Copps (an AGC developer, not an LVDC developer) for Hal Laning (also of Draper Labs); however the language itself was not developed by the Draper/Instrumentation Labs. The principle significance of the document for us, however, is that the study reveals a lot of detail about the existing LVDC software to which we're not otherwise privy.72-0005, CR-123570, "Flight Program Language Requirements", volume II of III, 03/07/1972, by T.

IV-4-401-1, 68-966-0002, Rev 1 August 1965, "Astrionics System Handbook, Saturn Launch Vehicles", missing chapters 10 and 11, 08/01/1965, by IBM Federal Systems Division. Chapter 11 is particularly relevant to the LVDC, as it discusses the flight software in some detail. Sadly, it does not show any actual sample snippets of LVDC software. You'll notice that we have three different revisions of this document. This earliest revision simply says that chapter 11 is "to be supplied later". One especially-important difference between the later two revisions, other than the fact that the final version has more-legible foldouts and is a much larger download, is that the aforementioned Chapter 11 has been completely rewritten between the 2nd and 3rd revisions: while the earlier version describes the LVDC software used in Apollo 11, the later version describes a new "generalized" LVDC program as used in Apollo 12. Another Apollo 12 vs 11 change is that the flight-sequence table (Chapter 4) differs.CR-71607, Rev 15 AUG 66, "Astrionics System Handbook, Saturn Launch Vehicles", 08/15/1966, by IBM Federal Systems Division.

I'm told that the particular hardcopy from which this scan came belonged to Donald R. Purdy, and that the handwritten notations in it are his. Don was one of the flight directors for Apollo 16, and (perhaps) a TELMU (Telemetry, Electrical, and EVA Mobility Unit Officer) for Apollo 14.

SM2A-03-SC014, First issue, "Apollo Operations Handbook, Command and Service Module, Spacecraft 014", volume 1, 10/17/1966, by North American Aviation. According to wikipedia, CSM-014's service module flew on Apollo 6, while its command module was disassembled as part of the Apollo 1 investigation and then later reassembled and used for ground testing.SM2A-03-SC012, "Apollo Operations Handbook, Command and Service Module, Spacecraft 012" or here, 11/12/1966, by North American Aviation.

LMA790-3-LM 2, Final, "Apollo Operations Handbook, Lunar Module 2 - Mission AS-205/208A", volume I of II, 01/01/1967, by Grumman Aerospace Engineering. LM-2, now in the Smithsonian NASM, was originally intended for mission AS-205/208A (incorrectly referred to sometimes in the document as AS-207/208A), the 2nd unmanned-LM test flight. However, that mission was cancelled due to the success of the 1st unmanned-LM test flight, so LM-2 was instead used for ground testing.SM2A-03-SC014-(2), Final, "Apollo Operations Handbook - Spacecraft 012 - Volume 2" or here, volume 2, Section 9, 01/27/1967, by Manned Spacecraft Center. Of the two scans, the primary one is much shorter, primarily because large sheets spanning multiple frames in the secondary scan comprise single pages in the primary scan. However, the scans appear to have been made from different physical hardcopies, and do differ in other ways in terms of readability and inclusions. This is just a fragment of the full document, and the metadata I've provided (date, title, revision, document number) is speculative. While it does have accompanying metadata, as well as a link providing additional metadata to the archive from which it came, that metadata isn't fully correct, thus forcing some guessed corrections from me. But from the page markings, it is clear that it relates to Apollo 1 (Spacecraft 012) and to the Apollo Operations Handbook. The date I've listed, 1/27/1967, comes directly from the page markings, and coincidentally was the exact day of the fire that destroyed the spacecraft. The document revision, "FINAL", is also what's marked on the pages. All of that, combined with these being "malfunction" procedures, is a bit too on the nose. Thankfully, none of the listed procedures relate to fires in the cockpit.SM2A-03-BLOCK II-(1), First issue, "Apollo Operations Handbook - Block II Spacecraft, Volume 1: Spacecraft Description", volume 1 of 2, 03/01/1967, by Manned Spacecraft Center.

This revision is identical the preceding revision ("Final") in our library, except that it includes the entirety of Section 9 ("Malfunction Procedures"), which the earlier revision did not.SM2A-03-SC101-(2), "Apollo Operations Handbook - CSM-101 - Volume 2: Flight Crew Operational Procedures", volume 2, Section 6, 1968, by Manned Spacecraft Center. This is just a fragment of the full document, and the metadata I've provided (date, title, document number) is speculative. While it does have accompanying metadata, as well as a link to the archive from which it came, that metadata isn't fully correct. However, because of the several references in the document fragment to Sundisk software (Apollo 7), and a handwritten "Swigert" (one of the Apollo 7 backup crew), it is reasonable to associate this with CSM-101 and the Apollo 7 mission.LMA790-3-LM3, "Apollo Operations Handbook - Lunar Module 3", volume II of II, 01/01/1968, by Grumman Aerospace Engineering.

It's too bad that these are only the change pages, and that we don't have the baseline document, but that's life! Note that we do have a later revision (3 February 1969) elsewhere in the collection, but only of a single section.

The versioning of the pages in this excerpt does not agree with the only other revision of Volume 2 that we have, namely 9/26/71. Rather, it is apparently a 1/15/71 version, and hence it's unclear which particular LMs are covered. The dates would agree with Apollo 14, however, and hence it's not unreasonable to suppose that these excerpts are specific to LM-8.LMA790-3-LM 10 and Subsequent, "Apollo Operations Handbook, Lunar Module, LM-10 and Subsequent" or here, volume I of II, 04/01/1971, by Grumman Aerospace Engineering.

The AS-206 Restart Alternate Mission, though only an unflown backup mission for the also-canceled AS-206A mission, remains significant today, due to the fact that it is the only mission for which the Saturn launch vehicle's LVDC software is known to have survived. At this writing, I am loath to post that software online, because it may be subject to severe "exporting" penalties under U. S. ITAR regulations. Its release is authorized only to "United States persons", which includes citizens and some others. If you want the software, and can convincely demonstrate that you are a U.

Note particularly Table 20 (PDF p. 247), which is a list of the LVDC presets. While we don't presently have LVDC flight-program source code for Apollo 14, the listed variables agree largely (or entirely) with those in the Apollo 17 LVDC flight program, so it's possible these values would be mostly okay for Apollo 15-17 as well. While the launch-vehicle operational trajectory documents (as opposed to the spacecraft trajectory documents) do generally include tables of LVDC presettings, this is the only one I'm presently aware of that chooses to tell us the numerical addresses at which the (named) variables being preset actually reside.C.

It is filled with hand-written notations which were apparently already on the document at the time it was scanned, although there is no claim that they were necessarily written there by Mike Collins.NASA.

The poor quality of this scan is due to my (RSB) experiments with cost-saving and time-reduction, rather than to the quality of the archival material. By the way, this document is for a Block I spacecraft, using SUNSPOT software. AC Electronics. This is pretty preliminary. It's interesting — your opinion may vary — that it appears to be based on SUNRISE 69 AGC software, as opposed to the SUNSPOT (247?) software that would have flown in Apollo 1. To the best of my present understanding, CORONA was forked from SUNRISE 69, and SUNSPOT was eventually branched from CORONA 261. Thus over 500 software revisions of CORONA and SUNSPOT existed between the one on which these reference cards are based and the one which would have flown.

Of the two scans, the primary one is much shorter, primarily because large sheets spanning multiple frames in the secondary scan comprise single pages in the primary scan. However, the scans appear to have been made from different physical hardcopies, and do differ in other ways in terms of readability and inclusions. This is just a fragment of the full document, and the metadata I've provided (date, title, revision, document number) is speculative. While it does have accompanying metadata, as well as a link providing additional metadata to the archive from which it came, that metadata isn't fully correct, thus forcing some guessed corrections from me. But from the page markings, it is clear that it relates to Apollo 1 (Spacecraft 012) and to the Apollo Operations Handbook. The date I've listed, 1/27/1967, comes directly from the page markings, and coincidentally was the exact day of the fire that destroyed the spacecraft. The document revision, "FINAL", is also what's marked on the pages. All of that, combined with these being "malfunction" procedures, is a bit too on the nose. Thankfully, none of the listed procedures relate to fires in the cockpit.R-477, "Guidance and Navigation System Operations Plan, Apollo Mission 202", 01/1965, by John M.

SUNDIAL E is a Block II AGC program that was "flown" the series of missions known as 2TV-1. These missions were crewed, but took place on the ground, and were used for thermal/vacuum testing of the CSM. Additionally, SUNDIAL E was used for acceptance testing of G&N systems. The present source code was reconstructed, using other known AGC source code as a resource. It assembles identically to octal data dumped from physical SUNDIAL E core-rope memory modules.See also:

SUNDIAL E was Block II CM AGC software never intended for flight. Rather, it was used for ground-based checkout of the CM G&N system, using elaborately-devised procedures. It was apparently the software used for the 2TV-1 (Block II Thermal Vacuum no. 1) CM AGC, and in that sense "flew" 4 missions, even though it never left the ground. We unfortunately do not have a contemporary listing of SUNDIAL E source code. Nor do we presently have reconstructed source code for it. What we do have is a core dump of the physical memory modules from an AGC owned by the MIT Museum. This core dump can be disassembled into user-unfriendly AGC source code — i.e., source code without embedded remarks, in which arbitrary labels are used instead of meaningful variable names and subroutine name — but we are not presently providing such a disassembly. Hopefully, we will eventually have a human-friendly reconstruction of the disassembled source code, but so far that has proven to be a challenge which hasn't been addresssed. Of course, with the core dump, SUNDIAL E can still be run our AGC CPU emulator (yaAGC); no source code needed for that!See also:

The poor quality of this scan is due to my (RSB) experiments with cost-saving and time-reduction, rather than to the quality of the archival material. Though the title does not say so, this document pertains to using an AGC loaded with AURORA 88 software. The use of AURORA is significant, because it is the last AGC program that includes a full suite of built-in-test code; LUMINARY and COLOSSUS, in contrast, contain only the code for checking the memory-rope checksums. Furthermore, this document is significant in that it provides a better understanding of how to use the test facilities in AURORA. The archive had earlier revisions of the document as well as the ones I scanned, but it appeared to me that they comprised perhaps 800 additional scans, and there wasn't time available at that point to do the extra scanning needed to acquire those earlier revisions. AC Electronics. AC Electronics. System Test Group Memo #824, "Changes made to AURORA 85 Program for Re-release as AURORA 88", 08/02/1966, by George Silver. MIT Instrumentation Laboratory. AURORA was the successor to RETREAD, and like RETREAD it never flew any missions. We have three records of AURORA being manufactured as memory modules, but those seem to reduce to only two actual releases: AURORA 85 (p/n 2021101-011) in March 1966 and AURORA 88 (p/n 2021101-021) in July 1966. Unfortunately, this doesn't seem to correlate too well with our own printout of AURORA, which according to the printout is REVISION 12 OF PROGRAM AURORA BY DAP GROUP, with the assembly having been run on November 10, 1966. Why was an assembly of AURORA 12 being made in November 1966, when AURORA 88 had already been released in July? The answer is that AURORA 12 was not being assembled or printed in November 1966, but that our assembly listing is instead that of a program (which I call "DAP AURORA"), which was forked by the Digital Autopilot (DAP) Group from the true AURORA at either AURORA 86 or AURORA 87. After being forked, the DAP Group apparently used it for developing the SUNBURST program, and there's a lot of buggy SUNBURST code appended to the end. (By which I mean, past the last of the memory sectors used by true AURORA.) In other words, what we have here is indeed revision 12, but it is revision 12 of DAP AURORA rather than revision 12 of true AURORA. See also:

These are the Apollo 8 flight-crew logs, as filled out by the crew, plus supplementary information about the mission. Elsewhere in the library, you'll find the blank forms for some of this content, as well as copies with hand-notations differing from this collection, presumably made by somebody other than the flight crew, or at least not made during the mission itself; so don't confuse those with these. I am told that NASA made about 15 sets of photocopies like this (with this scan being from set #15) for use by NASA executives, on heavy-stock 11" by 17" paper, as reference data for later missions. Regarding the two different links to the document, the second link is the archival copy while the first is a reduced-size PDF. The second copy is indeed more-legible than the first, as well it ought to be at about 30× the file size! Therefore, which is more suitable may depend very much on the specifics of what you're trying to get from them.Manned Spacecraft Center. Manned Spacecraft Center.

An example pointed out to me is the complete flagbit listing ... which we would normally find in the source code, but can't in this case since we don't have a contemporary listing of SUNDANCE, and only have attempted reconstructions. The two revisions of the document have almost exactly the same number of pages, so plenty of information must also have been added in the later one that's missing in this earlier one. Perhaps whoever prepared them was told to "keep it under 500 pages".2003972-451, "Rope-memory module B2 for SUNDANCE 302", 07/1968, by MIT Instrumentation Laboratory.

From the fact that this is for LM-4, and uses AGS Flight Program 4 (FP4), we might infer that FP4 was used for Apollo 10. But that's not true. The E mission for which this test plan was devised was later canceled, and the LM-4 AGS was reloaded with FP5 instead. But the verification of FP3/FP4 stands!Manned Spacecraft Center.

SUNDANCE 306 was the LM software for Apollo 9, and is the only version of SUNDANCE which ever flew. But we do not have a listing of its source code. What we do have is a set of dumps of core-memory modules, of various revisions of SUNDANCE, from various people's private collections, and an attempt by Mike Stewart to use this hodge-podge of material to recreate SUNDANCE 306 from them. Of the 6 core-rope modules, we actually have 7 dumps:See also:

The document describes using a modified version of COLOSSUS 226. Table 7-1 specifically lists the differences, in octal, between COLOSSUS 226 and the modified program. The changes are tantalizing similar to the changes to SUNDISK 281/282 listed in Table 7-1 of the generic Mission Evaluation Presimulation Report. I think they could be used to provide an extremely limited correspondence between some small areas in SUNDISK 282 vs COLOSSUS 226 ... assuming, of course, that we had the code for any of them, which we do not!2021111-041, "Assembly Listing of AGC Program COLOSSUS 249", 10/28/1968, by MIT Instrumentation Laboratory. COLOSSUS 249 flew as the CM AGC software on Apollo 9. The hardcopy from which the scanned pages were made was apparently printed on a page-printer that was not equipped with the intended character set used by the line printer(s) that printed all other AGC software listings in our possession, with the result that a number of characters were confusingly replaced by unintended alternatives.

Note that we do have a later revision (3 February 1969) elsewhere in the collection, but only of a single section. And we do have a complete Volume I for each of LM-3 and LM-6, so I suppose much of the info for LM-4 can be interpolated from them.LNY-22, "Control of command mode", 11/15/1968, by Kalan. 2021112-011, "Assembly Listing of AGC Program LUMINARY 69", 11/25/1968, by MIT Instrumentation Laboratory. This seems to have been the first LUMINARY revision targeted at the Apollo 10 mission, and seems additionally to have been the first revision of LUMINARY for which core-rope modules were manufactured. In other words, it was the first non-developmental revision of LUMINARY and the first released for manufacturing. Nevertheless, it ended up not being flown in the mission. For that, see LUMINARY 69 Rev 2.See also:

We do not have any actual contemporary listings of the source code. But the software has been reconstructed with almost-perfect confidence by Mike Stewart. That was possible because the following elements were all present:See also:

This is the first software release of COMANCHE targeted for Apollo 10 whose rope-memory modules were manufactured, but it was superseded and did not fly. We have no contemporary source-code listing for it at present, although a listing is known to have survived. The source code has, however, been reconstructed by Mike Stewart, with the expectation of 100% accuracy. The reconstruction began with known-good source code from the closely-related COMANCHE 51; in response to documentation about the changes between COMANCHE 44 and 51 found in various PCRs, PCNs, and Software Anomaly Reports, older code related to those changes was pulled in from the known-good COLOSSUS 249 source code. The end result was verified by the fact that its memory-bank checksums matched those for COMANCHE 44 listed in engineering drawing 2021153. Comments were also added to our transcription of the source code, for each of the differences between COMANCHE 44 and 51, so if you're interested you can view the changes in context by looking at either our code transcription or our colorized assembly listing. Mike also provided a detailed description of what he did, as he did it.See also:

We have no contemporary software listing for it. Mike Stewart has reconstructed the source code, however, with what we think is 100% fidelity. The reconstruction process is essentially the same as described in the comment for COMANCHE 44, except that it started wtih COMANCHE 45 and COMANCHE 51 as baselines and was overall easier to accomplish, so I'll just direct you the COMANCHE 44 comment to get a general idea of how the reconstruction process worked. Interestingly, there is an additional accuracy confirmation (beyond just matching of memory bank checksums in engineering drawing 2021153) which we don't have in most of the AGC software reconstructions. Months after reconstruction had completed, a contemporary user manual for the GAP program (the contemporary assembler used) turned up. In an Appendix at the back was a complete core dump of one of the COMANCHE 45 Rev 2 memory banks, as well as partial dumps of two other memory banks, and a complete list of differences between the core dumps of COMANCHE 45 vs 45 Rev 2. In all cases, the data in the GAP manual's Appendix matches the actual reconstruction.See also:

Comanche 51 was the software release initially intended to be used in the Apollo 11 Command Module. Its rope-memory modules were manufactured, but it was superseded and never flew. We do not have a contemporary listing of the source code, but it has been reconstructed with, we believe, 100% confidence. Mike Stewart has written up an explanation of the reconstruction process. In brief: We had the known-good source code for Comanche 55, and we knew that the difference between Comanche 51 and 55 was the addition of the so-called R-2 lunar potential model. Therefore, if the code for the R-2 lunar potential model were removed from the source code for Comanche 55, we should have the source code for Comanche 51. The R-2 model had also been added to LUMINARY, so the implementation details of how that related to the actual source code were relatively clear. Having made these changes, engineering drawing 2021153 contains a list of memory-bank checksums for the COMANCHE rope modules which had been manufactured, including the checksums for COMANCHE 51. The checksums do agree.See also:

CF-R-69-23, Rev A, "LM Rendezvous Procedures, G Mission", 06/20/1969, by Stephen P. Grega, Clark M. Neily. The cover was autographed by the crew. Covers not only the G mission (Apollo 11), but also H missions (12-14). We don't know if they applied to the J missions (14-17). Clark Neily, who co-authored the document and gave it to us (as well as the next two documents below), tells us that "my recollection is by that time, we had so much confidence in the systems and software that on the last two missions, they just boosted themselves into a 10 × 50 nm with a 'tweak' burn right after insertion followed by TPI about an 2-30 minutes later." Clark also has the following editorial comments. In understanding the comments, you probably need to know that since Clark is obviously a rendezvous expert, I had asked him a question about LORS (Lunar Optical Rendezvous System). This was apparently a potential competitor to the Rendezvous Radar that was eventually used in the LM, but it was cut out because the AGC code for it was 1500 words longer than the corresponding RR code. At any rate,Max Faget was a fanatical advocate of the optical tracker as the primary rendezvous navigation sensor. If he had had his way there would have been no rendezvous radar. This was an undocumented chapter in the Apollo program known to those of us who participated as the Rendezvous Wars. Under our tutelage, supported by extensive in-house Monte-Carlo analyses, the Astronaut Office took an uncompromising position on behalf of the radar as the primary rendezvous navigation system.
The wars continued into the Shuttle program, and were lost by our side because the FOD was able to make the case that they could support all rendezvous operations with ground-based tracking, and there was therefore no argument for autonomous on-board capability. Max got his way on the Shuttle, there was no rendezvous radar. By that time I was back in Houston working for a small company under contract to MPAD for orbital operations analysis. I got fired for refusing to lie to Draper about the availability of reference mission data to support some independent analysis they were doing for my former colleagues in SED. Thus ended my involvement in the wars, and I've always treasured those memories.
This document contains nomographs for computing the TPI and M/C maneuvers using LM boresight elevation angle measurements, and raw rendezvous radar data from the tape-meter readout. During the months prior to Apollo 11, I was able to use the GN&C analysis program in Monte-Carlo mode to construct computation tables for the CDH and CSI burns. This was done by perturbing the trajectory about the nominal, and developing power-series expansion functions for the maneuvers in terms of the resulting radar range and range-rate perturbations, obtained from measurements at fixed intervals before each burn. We wanted to be able to verify the on-board maneuver solutions independently of the ground, or in extremis do without them altogether, and still carry out the rendezvous as long as we had an operating radar. Hence our fanatical determination to have the radar as the primary rendezvous sensor. I'm not sure these nomographic and tabular backups were known to the Instrumentation Lab. They were brute force, but they worked. Never needed, though; the IL software and systems were iron-bottomed and gold-plated... [ellipsis Clark's]

I'm pretty sure that Don simply recycled the folder, which must previously have held content related to the DIANA program.EG7-71-73, "LGC Throttling Commands After Lunar Touchdown", 04/28/1971, by Robert G.

The first is to provide a functional description (operationally oriented) of the LM GNCS hardware and software and the interfaces with other spacecraft systems. The level of detail is that required to identify and define telemetry outputs. Also included are function flow diagrams of the LUMINARY programs and routines together with lists of verbs, nouns, option codes, and checklist codes for this flow. The second purpose is to provide the operational procedures for this hardware and software including nominal airborne condensed checklists, malfunction procedures, and program notes.".

Note particularly Table 20 (PDF p. 247), which is a list of the LVDC presets. While we don't presently have LVDC flight-program source code for Apollo 14, the listed variables agree largely (or entirely) with those in the Apollo 17 LVDC flight program, so it's possible these values would be mostly okay for Apollo 15-17 as well. While the launch-vehicle operational trajectory documents (as opposed to the spacecraft trajectory documents) do generally include tables of LVDC presettings, this is the only one I'm presently aware of that chooses to tell us the numerical addresses at which the (named) variables being preset actually reside.Allan Klumpp. This was a simulation run by AGC software developer Allan Klumpp. It had some problem which caused it to abort, so the simulation data isn't of much use (because there isn't any!), but it includes various info able pad loads that may be useful.Allan R.

Its rope-memory modules were manufactured, but the program was superseded and never flew. We do not have a copy of one of the original ARTEMIS 71 program listings, but it turns out to be possible to reconstruct its source code with confidence from the source code for ARTEMIS 72. Mike Stewart has written up a full explanation of how he did it. It is significant that we have engineering drawing 2021154, which lists the memory-bank checksums of ARTEMIS 71. The reconstructed program's checksums do agree with the listed ones.See also:

Stokes, Jr.If you're really paying close, close attention, you may wonder why all of our information on the COLOSSUS page and this page indicates that the same software was used for the Apollo 15-17 CM, namely ARTEMIS 72, and yet the linked document indicates ARTEMIS 72(REV1) instead. Conversely, the Apollo 15 document linked above indicates merely ARTEMIS 72 without a revision. Sounds different, doesn't it? Well, we don't presently have enough information to resolve this puzzling paradox with satisfying certainty. However, Nik Beug points out that the Operational Data Book actually does list ARTEMIS 72 REV 1 for Apollo 16 as well, while Mike Stewart points out that the AGC's memory modules have the same manufacturing dash numbers for Apollo 15 and 16 (indicating that they had the same software loads stored in them). This lends a lot of credence to the notion that all three of these missions really did have the same software load. Plus, you have other support, such as memos like this one. But whether that software version was ARTEMIS 72 or whether it was ARTEMIS 72 REV 1 is still unclear, and the available data allows it to be argued either way.Russel Larson.

Its rope-memory modules were manufactured, but the program was superseded and never flew. We do not have a copy of one of the original ARTEMIS 71 program listings, but it turns out to be possible to reconstruct its source code with confidence from the source code for ARTEMIS 72. Mike Stewart has written up a full explanation of how he did it. It is significant that we have engineering drawing 2021154, which lists the memory-bank checksums of ARTEMIS 71. The reconstructed program's checksums do agree with the listed ones.See also:

FS66-72-149, "Final Apollo 17 Prelaunch Erasable Load COLOSSUS III (ARTEMIS 72)", 1972, by James C. Stokes, Jr.If you're really paying close, close attention, you may wonder why all of our information on the COLOSSUS page and this page indicates that the same software was used for the Apollo 15-17 CM, namely ARTEMIS 72, and yet the linked document indicates ARTEMIS 72(REV1) instead. Conversely, the Apollo 15 document linked above indicates merely ARTEMIS 72 without a revision. Sounds different, doesn't it? Well, we don't presently have enough information to resolve this puzzling paradox with satisfying certainty. However, Nik Beug points out that the Operational Data Book actually does list ARTEMIS 72 REV 1 for Apollo 16 as well, while Mike Stewart points out that the AGC's memory modules have the same manufacturing dash numbers for Apollo 15 and 16 (indicating that they had the same software loads stored in them). This lends a lot of credence to the notion that all three of these missions really did have the same software load. Plus, you have other support, such as memos like this one. But whether that software version was ARTEMIS 72 or whether it was ARTEMIS 72 REV 1 is still unclear, and the available data allows it to be argued either way.72-FM-39, MSC-06016, "Spacecraft Operational Trajectory for Apollo 16 (Mission J-2)", volume II of II, 02/10/1972, by Manned Spacecraft Center.

Its rope-memory modules were manufactured, but the program was superseded and never flew. We do not have a copy of one of the original ARTEMIS 71 program listings, but it turns out to be possible to reconstruct its source code with confidence from the source code for ARTEMIS 72. Mike Stewart has written up a full explanation of how he did it. It is significant that we have engineering drawing 2021154, which lists the memory-bank checksums of ARTEMIS 71. The reconstructed program's checksums do agree with the listed ones.See also:

Stokes, Jr.If you're really paying close, close attention, you may wonder why all of our information on the COLOSSUS page and this page indicates that the same software was used for the Apollo 15-17 CM, namely ARTEMIS 72, and yet the linked document indicates ARTEMIS 72(REV1) instead. Conversely, the Apollo 15 document linked above indicates merely ARTEMIS 72 without a revision. Sounds different, doesn't it? Well, we don't presently have enough information to resolve this puzzling paradox with satisfying certainty. However, Nik Beug points out that the Operational Data Book actually does list ARTEMIS 72 REV 1 for Apollo 16 as well, while Mike Stewart points out that the AGC's memory modules have the same manufacturing dash numbers for Apollo 15 and 16 (indicating that they had the same software loads stored in them). This lends a lot of credence to the notion that all three of these missions really did have the same software load. Plus, you have other support, such as memos like this one. But whether that software version was ARTEMIS 72 or whether it was ARTEMIS 72 REV 1 is still unclear, and the available data allows it to be argued either way.R-577, Rev 14, "Guidance System Operations Plan for Manned CM Earth Orbital and Lunar Missions Using Program COLOSSUS 3, Section 3: Digital Autopilots", section 3, 03/1972, by MIT Instrumentation Laboratory.

This is one of the series of AC/Delco documents we've been calling "Apollo 11 Manual", "Apollo 16 Manual", and so on. The term "Program Description" in the title seems to be a change in the naming practice rather than in the nature of the document itself. The document itself is undated, but the last events referred to in the book are in June 1973, so I've pretended that the book was published immediately thereafter.MPR-SAT-FE-73-3, TM X-69538, "Saturn IB Launch Vehicle Flight Evaluation Report — SA-206, Skylab-2", 07/23/1973, by NASA.

This fascinating "document" helped in reconstructing Skylark 48 source code from dumps of physical core-rope memory modules. I've quoted "document" because it's not clear if this is a fragment of some other document, or whether it's simply an ad hoc aid somebody created during Skylark development without any notion of it being in any way official. It has neither a title, date, nor any attributed authorship. I've assigned it to 1975 and to the Instrumentation Lab simply because the Apollo-Soyuz Test Project (ASTP) mission was the last flight of the Skylark software ... or indeed any other Apollo-type AGC mission.FS52-75-5, Preliminary, "Apollo Soyuz Test Project (ASTP) Command Module Computer (CMC) Preliminary Erasable Load", 02/01/1975, by James C.

I've quoted "document" because it's not clear if this is a fragment of some other document, or whether it's simply an ad hoc aid somebody created during Skylark development without any notion of it being in any way official. It has neither a title, date, nor any attributed authorship. I've assigned it to 1975 and to the Instrumentation Lab simply because the Apollo-Soyuz Test Project (ASTP) mission was the last flight of the Skylark software ... or indeed any other Apollo-type AGC mission.FS52-75-5, Preliminary, "Apollo Soyuz Test Project (ASTP) Command Module Computer (CMC) Preliminary Erasable Load", 02/01/1975, by James C.

These quick-reference cards, presumably used for training flight controllers, packed a lot of info about Skylark (and indirectly about Colossus and to a lesser extent Luminary) in a very concise package.FS63-73-61, "Skylab CMC Erasable Final Erasable Load", 04/24/1973, by James C.

This fascinating "document" helped in reconstructing Skylark 48 source code from dumps of physical core-rope memory modules. I've quoted "document" because it's not clear if this is a fragment of some other document, or whether it's simply an ad hoc aid somebody created during Skylark development without any notion of it being in any way official. It has neither a title, date, nor any attributed authorship. I've assigned it to 1975 and to the Instrumentation Lab simply because the Apollo-Soyuz Test Project (ASTP) mission was the last flight of the Skylark software ... or indeed any other Apollo-type AGC mission.NASA.

According to our best understanding at present, the symbol Φ is the gravitational potential. Gene adds that he thinks that "the angle, phi (f) in the three-term expansion of the earth's oblate geo-gravity model, is measured from the ascending node of a Gemini orbit rather than latitude.". Anonymous. A summary of the OBC, its software, and peripherals in 80 pages.Gene Mertz. Gene Mertz. A hand-written memo, presumably by Gene Mertz, regarding issues such as roundoff and step size in the Gemini orbital calculation.Gene Mertz. There are some hand-drawn corrections on the first page that may be hard to read. In two places it say "t+h", and later in the same paragraph, the y in "y=f(t)" has been dotted.62-564-0020, "Gemini Computer Math Flow Diagram Ascent", appendix E only, 01/31/1963, by Anonymous. The ascent-guidance math flow begins on p. 3 of the linked document. I'm unclear on the relationship of this math flow to our copy of the presumed MF-2 math flow. It appears generally similar, but it's so different in appearance that you can't really tell at a glance how similar they are ... and I haven't reallly done the work needed to compare them in detail. They also have different drawing numbers, in that the ascent guidance here is 62-564-0020 rather than 6444540 S/N2. From the dates on the drawings, and from the information in the "abbreviated" Gemini software history, it appears to me that:63-564-0159, "Preliminary Ascent Guidance Simulation Report (Analytic Report No. 6)" or here, 01/31/1963, by D.

Includes OBC developer Alden Minnick's handwritten notes. (The illegible notes at the left margin of p. 17 are: "TE = AT LIFT OFF T" and "TE > TE0 = LIFT OFF".) The entire math flow comprises 27 sheets, labeled "Size F", which is apparently 28×40 inches, so it's pretty big. I don't see any markings indicating an overall version code, but the individual pages range from "initial" to Rev B. The latest date I can find on any drawing is 5/1/1963, so I assumed it's reasonable to just think of this as the 5/1/1963 version. Referring to the "Abbreviated Gemini Software History", I find that the only listed version that this could correspond to — assuming it corresponds to any of them — is math flow MF-2. Thus, I'd tentatively identify this with MF-2.SEDR 300, "Project Gemini Familiarization Manual, Long Range and Modified Configurations", volume 1 except Section VIII, 09/30/1965, by McDonnell Douglas.

This "report" actually contains the full source code for the mixed FORTRAN II and IBM 7090/7094 assembly language program that was used to verify algorithms and simulate flight-computer behavior for the Catch-Up and Rendezvous flight phases. Therefore, although it is not flight software per se, it is presently the closest thing we have to Gemini flight software. There are also 5 fold-out flowcharts which are split into multiple pages in the PDF, which I've pulled out, deskewed, rescaled, and rejoined. They're not perfect, but they're a little easier to read than the pages in the PDF file.H. F. Branning.

NASA. James E. Dobson, Rena J. Mosteirin. This is a book by poets, deriving poetry from the Apollo 11 AGC source code. In introducing the material, I seem to recall they remark that we — the Virtual AGC Project — got the AGC source code by OCR'ing the original program listing ... a canard! We had to type in every little smeckle of source code with our own fat little fingers! So don't you go around repeating this calumny. But still, they're poets and not journalists; and besides, for all I know, I may unintentionally be telling whoppers about them, just in this tiny comment. In other words, if that's the worst problem they have, they must be doing pretty well. If you like the book, go out and buy a hardcopy.Grumman Aerospace Engineering.

ND-1021042, "Apollo Lunar Excursion Module, Primary Guidance, Navigation, and Control System Manual" or here, volume I of II, 02/01/1966, by AC Electronics. If you have looked at our 1972 version of volume 1, you will have noted that roughly 175 pages are missing from that 1972 version. Those 175 pages are the ones discussing the theory of operation of the "control sequences" (microcode of the CPU) in detail. Those pages are not missing from this version! I daresay those pages form the most-extensive discussion of the Block II AGC microcode to which we have access.ND-1021042, "Apollo Lunar Excursion Module, Primary Guidance, Navigation, and Control System Manual" or here, volume II of II, 02/01/1966, by AC Electronics. This volume is notable because it contains a lot of electrical-schematic data for the Block II AGC, relating to stuff like (for example) decoding of the "control sequences" (microcode) of the CPU. Those schematics are not merely a supplemental form of the 1972 version of this document, but also differ from them in some significant ways.ND-1021042, Rev AJ, "Project Apollo Lunar Excursion Module Primary Guidance, Navigation, and Control System Manual" or here, volume I of II, minus pp. 4-1 through 4-176, 02/01/1966, by AC Electronics. Unfortunately, pages 1 through 176 in chapter 4 are missing in this scan. Incidentally, note that the table of contents incorrectly indicates where the break between volume I and volume II is (perhaps because the pages were reshuffled when the missing pages were removed), so don't let that confuse you. This missing pages are present in a 1966 version of the document that we also have, though obviously their content may have changed somewhat over the intervening 6 years. Several topics are covered in the missing pages, but the principal topic is the theory of operation of the CPU's "control sequences" (microcode).ND-1021042, Rev AJ, "Project Apollo Lunar Excursion Module Primary Guidance, Navigation, and Control System Manual" or here, volume II of II, 02/01/1966, by AC Electronics.

The ascent-guidance math flow begins on p. 3 of the linked document. I'm unclear on the relationship of this math flow to our copy of the presumed MF-2 math flow. It appears generally similar, but it's so different in appearance that you can't really tell at a glance how similar they are ... and I haven't reallly done the work needed to compare them in detail. They also have different drawing numbers, in that the ascent guidance here is 62-564-0020 rather than 6444540 S/N2. From the dates on the drawings, and from the information in the "abbreviated" Gemini software history, it appears to me that:63-564-0159, "Preliminary Ascent Guidance Simulation Report (Analytic Report No. 6)" or here, 01/31/1963, by D.

The entire math flow comprises 27 sheets, labeled "Size F", which is apparently 28×40 inches, so it's pretty big. I don't see any markings indicating an overall version code, but the individual pages range from "initial" to Rev B. The latest date I can find on any drawing is 5/1/1963, so I assumed it's reasonable to just think of this as the 5/1/1963 version. Referring to the "Abbreviated Gemini Software History", I find that the only listed version that this could correspond to — assuming it corresponds to any of them — is math flow MF-2. Thus, I'd tentatively identify this with MF-2.M-D M 8000.001, "Apollo System Specification", 05/02/1963, by NASA.

TRIVIUM is a sample AGC program presented in a document called "YUL Programming System", as an example of how to write and assemble an AGC program using the YUL assembler. It is the earliest AGC program presently known to us, though as its name implies, it is trival in nature. (Though knowing Hugh, he may have meant it had something to do with grammar, logic, and rhetoric ... which to a certain extent it does.) As short as the program is, it has several intentional errors in it, in order to illustrate YUL's errors and warnings.See also:

The document is actually undated, though there are stamps and signatures on it from 1970. From the visual aging of the document, however, it's unlikely (in my not-so-humble opinion) to have been created in 1970. The document number, 65ICD9304, may indicate that it was created in 1965. As for the stamps and signatures from 1970, I'd note that missions AS-206 through AS-210 were originally scheduled for 1967 or thereabouts, but were canceled after the Apollo 1 disaster. The launch vehicles were eventually repurposed for Skylab and ASTP missions, for which some preparations apparently began in 1970. I would therefore theorize that this preliminary document was revived in 1970 as part of the early preparations for Skylab missions, and that that's where the references to 1970 in it came from.E-1758, "Organization of Computation and Control in the Apollo Guidance Computer", 1965, by T. J. Lawton, C. J. Muntz. SISD-4 (2-2M) I2-65, "Apollo Guidance Computer", 1965, by Raytheon. Basically a Raytheon marketing brochure for the AGC and DSKY "products", created at a time when only the Block I system existed but the Block II system was "in design" ... targeted at whom? Fun quote: "Raytheon's Digital Systems staff welcomes your inquiries concerning design and application of this and similar equipment to your needs, and our staff can supply a wide range of analytical, design, and manufacturing talent to your programs' computer needs, be they airborne, spaceborne, or on the ground." It leaves out that the design targets an MTBF of something like 30 days. Although in my experience, such materials may have been created more as an advertisement for the company than in the serious expectation of a demand for the product, so perhaps that's the case here as well.R-477, "Guidance and Navigation System Operations Plan, Apollo Mission 202", 01/1965, by John M.

CR-124292, "Assembly Listing of PTC ADAPT Self-Test Program (LVDC)", volume V Chapter 7, 03/05/1965, by IBM Federal Systems Division. The Programmable Test Controller (PTC) is laboratory-based test equipment (LTE) associated with the LVDC. In fact, it contains a modified LVDC, for which the PTC ADAPT Self-Test Program is the software. In other words, this software is essentially an LVDC program, though with some small differences. The syntax is very slightly different from that of a standard LVDC program. The principal distinction we are aware of right now is that multiplication and division instructions are replaced by i/o instructions; i.e., multiplications and divisions are performed by some peripheral device rather than by the CPU itself. Because it is not guidance software — it is a self-test program — there is no reason to suppose that there is any restriction for its "export" under ITAR; thus, it is presented in full here. In any case, it's freely available elsewhere online, without restrictions. Comparatively, the source-code portion of the listing is 170 pages, whereas an LVDC flight program has around 300 source-code pages, so while the PTC ADAPT Self-Test Program is smaller than an LVDC Flight Program, it is not trivial in comparison either. It's worth noting that the software listing is found in Chapter 7 of the PTC manual, but that preceding it in the manual, you can also find the user instructions for running the program.See also:

Chapter 11 is particularly relevant to the LVDC, as it discusses the flight software in some detail. Sadly, it does not show any actual sample snippets of LVDC software. You'll notice that we have three different revisions of this document. This earliest revision simply says that chapter 11 is "to be supplied later". One especially-important difference between the later two revisions, other than the fact that the final version has more-legible foldouts and is a much larger download, is that the aforementioned Chapter 11 has been completely rewritten between the 2nd and 3rd revisions: while the earlier version describes the LVDC software used in Apollo 11, the later version describes a new "generalized" LVDC program as used in Apollo 12. Another Apollo 12 vs 11 change is that the flight-sequence table (Chapter 4) differs.FR-2-114, "Apollo Guidance Computer Information Series, Issue 14: Mode Switching and Mark", 08/01/1965, by Raytheon.

The poor quality of this scan is due to my (RSB) experiments with cost-saving and time-reduction, rather than to the quality of the archival material. Though the title does not say so, this document pertains to using an AGC loaded with AURORA 88 software. The use of AURORA is significant, because it is the last AGC program that includes a full suite of built-in-test code; LUMINARY and COLOSSUS, in contrast, contain only the code for checking the memory-rope checksums. Furthermore, this document is significant in that it provides a better understanding of how to use the test facilities in AURORA. The archive had earlier revisions of the document as well as the ones I scanned, but it appeared to me that they comprised perhaps 800 additional scans, and there wasn't time available at that point to do the extra scanning needed to acquire those earlier revisions. 66-FM-50, "Apollo Command Module Guidance Computer Software Requirements, Mission AS-204", 1966, by MSC. 66-FM-50, "Apollo Command Module Guidance Computer Software Requirements, Mission AS-205", 1966, by MSC. 66-FM-50, "Apollo Command Module Guidance Computer Software Requirements, Mission AS-207/208", 1966, by MSC. 66-FM-50, "Apollo Command Module Guidance Computer Software Requirements, Mission AS-502", 1966, by MSC. 66-FM-52, "Apollo Lunar Excursion Module Abort Guidance System Software Requirements, Mission AS-207/208", 1966, by MSC. 66-FM-51, "Apollo Lunar Excursion Module Guidance Computer Software Requirements, Missions AS-207/208(278)", 1966, by MSC.

What this document concerns is an alternate type of IMU which does not have a gimballed stable inertial platform the way the actual mission IMU did, but instead was "strapped down" to the spacecraft. In order to use such an IMU, it is necessary to be able to efficiently convert between a coordinate system fixed to the spacecraft and an inertial one, using only AGC integer computations, and this document shows that that is possible, as well as the fact that the strap-down IMU can achieve an adequate accuracy. The author, Jim Pennypacker, also offered me this observation:The document was prepared while I was working for Al Hopkins and Ray Alonso at the Instrumentation Laboratory and describes the analysis of the crux of a proposed backup system if the AGC became overloaded during the LEM trajectory. Although the backup method described was never used, the document shows the type of analysis that went on "behind the scenes" in support of the entire mission.

ND-1021042, "Apollo Lunar Excursion Module, Primary Guidance, Navigation, and Control System Manual" or here, volume I of II, 02/01/1966, by AC Electronics. If you have looked at our 1972 version of volume 1, you will have noted that roughly 175 pages are missing from that 1972 version. Those 175 pages are the ones discussing the theory of operation of the "control sequences" (microcode of the CPU) in detail. Those pages are not missing from this version! I daresay those pages form the most-extensive discussion of the Block II AGC microcode to which we have access.ND-1021042, "Apollo Lunar Excursion Module, Primary Guidance, Navigation, and Control System Manual" or here, volume II of II, 02/01/1966, by AC Electronics. This volume is notable because it contains a lot of electrical-schematic data for the Block II AGC, relating to stuff like (for example) decoding of the "control sequences" (microcode) of the CPU. Those schematics are not merely a supplemental form of the 1972 version of this document, but also differ from them in some significant ways.ND-1021042, Rev AJ, "Project Apollo Lunar Excursion Module Primary Guidance, Navigation, and Control System Manual" or here, volume I of II, minus pp. 4-1 through 4-176, 02/01/1966, by AC Electronics. Unfortunately, pages 1 through 176 in chapter 4 are missing in this scan. Incidentally, note that the table of contents incorrectly indicates where the break between volume I and volume II is (perhaps because the pages were reshuffled when the missing pages were removed), so don't let that confuse you. This missing pages are present in a 1966 version of the document that we also have, though obviously their content may have changed somewhat over the intervening 6 years. Several topics are covered in the missing pages, but the principal topic is the theory of operation of the CPU's "control sequences" (microcode).ND-1021042, Rev AJ, "Project Apollo Lunar Excursion Module Primary Guidance, Navigation, and Control System Manual" or here, volume II of II, 02/01/1966, by AC Electronics.

AS-207 (see the write-up at Encyclopedia Astronautica) and AS-208 were initially intended to be missions that launched CSM-101 into orbit on a Saturn IB (AS-207), while launching LM-2 into orbit on a separate Saturn IB (AS-208), and then rendezvousing the CSM and LM. Those original missions were canceled in the wake of the Apollo fire, and the launch vehicles eventually repurposed for Skylab missions. This document, of course, was written at the time of the originally-intended missions.Digital Development Memo #303, "Standby Operation in Pre-Installation Test", 03/14/1966, by Albert Hopkins.

It's interesting — your opinion may vary — that it appears to be based on SUNRISE 69 AGC software, as opposed to the SUNSPOT (247?) software that would have flown in Apollo 1. To the best of my present understanding, CORONA was forked from SUNRISE 69, and SUNSPOT was eventually branched from CORONA 261. Thus over 500 software revisions of CORONA and SUNSPOT existed between the one on which these reference cards are based and the one which would have flown.

The ground computer with which the LVDC cooperated was an RCA 110A.

These algorithms are each accompanied by RCA 110A assembly language showing exactly how they were implemented, and give the full theory for each method, duly written up as if the description were a mechanical drawing, with a proper page border appropriate to such a drawing, and accompanied by notations such as the units, scale, and tolerance of the drawing!

Peabody. MIT Instrumentation Laboratory. AURORA was the successor to RETREAD, and like RETREAD it never flew any missions. We have three records of AURORA being manufactured as memory modules, but those seem to reduce to only two actual releases: AURORA 85 (p/n 2021101-011) in March 1966 and AURORA 88 (p/n 2021101-021) in July 1966. Unfortunately, this doesn't seem to correlate too well with our own printout of AURORA, which according to the printout is REVISION 12 OF PROGRAM AURORA BY DAP GROUP, with the assembly having been run on November 10, 1966. Why was an assembly of AURORA 12 being made in November 1966, when AURORA 88 had already been released in July? The answer is that AURORA 12 was not being assembled or printed in November 1966, but that our assembly listing is instead that of a program (which I call "DAP AURORA"), which was forked by the Digital Autopilot (DAP) Group from the true AURORA at either AURORA 86 or AURORA 87. After being forked, the DAP Group apparently used it for developing the SUNBURST program, and there's a lot of buggy SUNBURST code appended to the end. (By which I mean, past the last of the memory sectors used by true AURORA.) In other words, what we have here is indeed revision 12, but it is revision 12 of DAP AURORA rather than revision 12 of true AURORA. See also:

Note that the final page is a table cross-referencing individual document numbers for missions AS-201 through AS-212, from which it can be seen that none of the drawings herein apply unchanged to any other mission; though for all I know, the necessary changes may be little more than updating the mission number in the sentence "REFERENCE INFORMATION FOR AS-207" found on most of the drawings' title blocks.North American Aviation.

SOLARIUM 55 flew as the CM AGC software on the unmanned Apollo 4 and Apollo 6 missions. In theory, SOLARIUM 54 is the software which officially flew on the unmanned Apollo 4 mission, but it's difficult to escape the conclusion that SOLARIUM 54 and 55 were identical even though given differing revision numbers for some reason. The Apollo 4 and 6 Command Modules were Block 1 spacecraft, and hence unlike almost all other AGC programs in our library, SOLARIUM is a Block 1 AGC program.See also:

Of the two scans, the primary one is much shorter, primarily because large sheets spanning multiple frames in the secondary scan comprise single pages in the primary scan. However, the scans appear to have been made from different physical hardcopies, and do differ in other ways in terms of readability and inclusions. This is just a fragment of the full document, and the metadata I've provided (date, title, revision, document number) is speculative. While it does have accompanying metadata, as well as a link providing additional metadata to the archive from which it came, that metadata isn't fully correct, thus forcing some guessed corrections from me.

The date I've listed, 1/27/1967, comes directly from the page markings, and coincidentally was the exact day of the fire that destroyed the spacecraft. The document revision, "FINAL", is also what's marked on the pages. All of that, combined with these being "malfunction" procedures, is a bit too on the nose. Thankfully, none of the listed procedures relate to fires in the cockpit.TM-X-66796, "Gemini Program Corrective Action Listing - Gemini I Through XII", 01/31/1967, by Manned Spacecraft Center. 67-EG-6, "A Study of Lunar Module Navigation Systems Accuracies for Powered Descent, Ascent, and Aborts", 01/31/1967, by Charles R.

Hugh Blair-Smith. This is the Honeywell H-800 source code of the original YUL assembler for AGC code. It was superseded by the GAP assembler, for which we have no source code. While YUL's source code is for the H-800 computer, it is not written in the H-800's assembly language, ARGUS, but is instead written in something called MITIGUS. We don't have an exact description of MITIGUS, nor the preprocessor software that converts MITIGUS to ARGUS ... which we'd have no way to run anyway. Nevertheless, as is our usual practice, we've transcribed the scanned assembly listing of YUL into source-code files, which are a bit more readable than the original scan!See also:

While it does have accompanying metadata, as well as a link to the archive from which it came, that metadata isn't fully correct.

In fact, we can't even say that it's LM software or CM software, but merely that it is AGC software. And it wasn't even written by the MIT Instrumentation Laboratory, but actually by Raytheon (the manufacturer of the AGC) instead. It was part of a test of an "auxiliary memory" system for the AGC. The auxiliary memory was a magnetic tape drive, from which programs could be loaded into the AGC in flight. Apparently the auxiliary memory worked, but it never ended up being used.See also:

An example pointed out to me is the complete flagbit listing ... which we would normally find in the source code, but can't in this case since we don't have a contemporary listing of SUNDANCE, and only have attempted reconstructions. The two revisions of the document have almost exactly the same number of pages, so plenty of information must also have been added in the later one that's missing in this earlier one.

The level of detail is that required to identify and define telemetry outputs. Also included are functional flow diagrams of the Sundisk 282 programs and routines together with lists of verbs, nouns, option codes, and checklist codes for this flow.

It's too bad that these are only the change pages, and that we don't have the baseline document, but that's life! Note that we do have a later revision (3 February 1969) elsewhere in the collection, but only of a single section. And we do have a complete Volume I for each of LM-3 and LM-6, so I suppose much of the info for LM-4 can be interpolated from them.W. M. Anderson.

The changes are tantalizing similar to the changes to SUNDISK 281/282 listed in Table 7-1 of the generic Mission Evaluation Presimulation Report. I think they could be used to provide an extremely limited correspondence between some small areas in SUNDISK 282 vs COLOSSUS 226 ... assuming, of course, that we had the code for any of them, which we do not!CR-130938, "Real Time Computer Complex - Apollo Programming Systems - Book: Mission Systems, Volume 1: AS-200 Mission Planning", volume 1/17, 10/21/1968, by IBM Federal Systems Division.

In other words, it was the first non-developmental revision of LUMINARY and the first released for manufacturing. Nevertheless, it ended up not being flown in the mission.

These are the Apollo 8 flight-crew logs, as filled out by the crew, plus supplementary information about the mission. Elsewhere in the library, you'll find the blank forms for some of this content, as well as copies with hand-notations differing from this collection, presumably made by somebody other than the flight crew, or at least not made during the mission itself; so don't confuse those with these. I am told that NASA made about 15 sets of photocopies like this (with this scan being from set #15) for use by NASA executives, on heavy-stock 11" by 17" paper, as reference data for later missions. Regarding the two different links to the document, the second link is the archival copy while the first is a reduced-size PDF. The second copy is indeed more-legible than the first, as well it ought to be at about 30× the file size! Therefore, which is more suitable may depend very much on the specifics of what you're trying to get from them.Manned Spacecraft Center. Manned Spacecraft Center.

CF-R-69-23, Rev A, "LM Rendezvous Procedures, G Mission", 06/20/1969, by Stephen P. Grega, Clark M. Neily. The cover was autographed by the crew. Covers not only the G mission (Apollo 11), but also H missions (12-14). We don't know if they applied to the J missions (14-17). Clark Neily, who co-authored the document and gave it to us (as well as the next two documents below), tells us that "my recollection is by that time, we had so much confidence in the systems and software that on the last two missions, they just boosted themselves into a 10 × 50 nm with a 'tweak' burn right after insertion followed by TPI about an 2-30 minutes later." Clark also has the following editorial comments. In understanding the comments, you probably need to know that since Clark is obviously a rendezvous expert, I had asked him a question about LORS (Lunar Optical Rendezvous System). This was apparently a potential competitor to the Rendezvous Radar that was eventually used in the LM, but it was cut out because the AGC code for it was 1500 words longer than the corresponding RR code. At any rate,Max Faget was a fanatical advocate of the optical tracker as the primary rendezvous navigation sensor. If he had had his way there would have been no rendezvous radar. This was an undocumented chapter in the Apollo program known to those of us who participated as the Rendezvous Wars. Under our tutelage, supported by extensive in-house Monte-Carlo analyses, the Astronaut Office took an uncompromising position on behalf of the radar as the primary rendezvous navigation system.
The wars continued into the Shuttle program, and were lost by our side because the FOD was able to make the case that they could support all rendezvous operations with ground-based tracking, and there was therefore no argument for autonomous on-board capability. Max got his way on the Shuttle, there was no rendezvous radar. By that time I was back in Houston working for a small company under contract to MPAD for orbital operations analysis. I got fired for refusing to lie to Draper about the availability of reference mission data to support some independent analysis they were doing for my former colleagues in SED. Thus ended my involvement in the wars, and I've always treasured those memories.
This document contains nomographs for computing the TPI and M/C maneuvers using LM boresight elevation angle measurements, and raw rendezvous radar data from the tape-meter readout. During the months prior to Apollo 11, I was able to use the GN&C analysis program in Monte-Carlo mode to construct computation tables for the CDH and CSI burns. This was done by perturbing the trajectory about the nominal, and developing power-series expansion functions for the maneuvers in terms of the resulting radar range and range-rate perturbations, obtained from measurements at fixed intervals before each burn. We wanted to be able to verify the on-board maneuver solutions independently of the ground, or in extremis do without them altogether, and still carry out the rendezvous as long as we had an operating radar. Hence our fanatical determination to have the radar as the primary rendezvous sensor. I'm not sure these nomographic and tabular backups were known to the Instrumentation Lab. They were brute force, but they worked. Never needed, though; the IL software and systems were iron-bottomed and gold-plated... [ellipsis Clark's]

The first is to provide a functional description (operationally oriented) of the LM GNCS hardware and software and the interfaces with other spacecraft systems. The level of detail is that required to identify and define telemetry outputs. Also included are function flow diagrams of the LUMINARY programs and routines together with lists of verbs, nouns, option codes, and checklist codes for this flow.

PCR-?, "Attitude Command During Manually-Controlled Lunar Landing", 12/03/1969, by R. F. Stengel. Our copy of this PCR does not have a PCR number on it, nor indicate any disposition. On the other hand, PCR-885, rejected by the SCB, had the very similar title "Attitude command during manual landings". But it does not seem as though this PCR should be identified with PCR-885, because this PCR is dated 12/03/1969, whereas the SCB rejected PCR-885 on 10/09/1969. Moreover, a 12/02/1969 memo by this PCR's author is attached to the PCR, and it discusses the prior rejection of PCR-885. The memo, however, mentions neither this PCR, nor gives any reasons why this PCR would be more acceptable to the SCB than PCR-885 had been. Possibly this is a revision of PCR-885.LUMINARY Memo #129, "LUMINARY Revisions 131", 12/05/1969, by Dana Densmore. Philip G. Felleman. Russell A. Larson.

However, there were eventually two later releases (LUMINARY 131 Rev 9 and LUMINARY 131 Rev 1 ... and no, that's not a misprint) due to bug fixes, so LUMINARY 131 never flew. It is, however, the closest thing we presently have to Apollo 13 LM software.See also:

SIMFAM is a "braid memory" adapter used for ground testing of the AGC, allowing you to use braid memory in place of the AGC's normal core memory. There is a (paywalled) 1966 paper about braid memory in the IEEE Transactions on Electronic Computers, by Aldrich and Alonso. "Braid memory" is apparently a term invented by the authors of the paper. It is a form of "transformer memory". Transformer memory, to quote the paper, "make[s] use of magnetic coupling, linear, or nonlinear, between a set of interrogation lines and a set of sense lines. ... The appeal of such memories is based on the permanence of the information, which is of advantage in control systems, and on the intuitive feeling that it should be possible to build large (about 106 bits), fast (about 1μs cycle time), fixed memories at a cost substantially below that of equivalent core storage," in spite of the fact that the cost of core memory was "rapidly dropping" at that time. In particular, the "braid" variety of transformer memories, based on something called a Dimond switch, could be manufactured by being woven on a loom in order to reduce manufacturing cost. Each "braid" is a string of transformers, with each step of the weaving process adding another transformer to the string, so the speed of manufacture could be increased simply by having the loom simultaneously operate on more braids in parallel. They mention that a 64-string loom was in operation and that a 256-string loom was under development.MIT Instrumentation Laboratory.

MIT Instrumentation Laboratory. ZERLINA is a branch of main LUMINARY source code, which could be treated as a workbench for trying out ideas without fear of affecting LUMINARY. Ideas which proved valuable could then be ported back from ZERLINA into LUMINARY. The largest such idea that I'm aware of that was treated in this way was the "variable servicer", which reduced CPU usage by omitting certain guidance computations when they weren't really needed, as opposed to inflexibly recomputing them at fixed intervals. By thus keeping the CPU usage at an overall lower percentage during lunar descent, the probability of overloads causing 1201/1202 alarms such as those in the Apollo 11 landing would be greatly reduced. (Yes, I know that the 1201/1202-alarm overloads were caused by the Rendezvous Radar being unexpectedly active, from the AGC's point of view. But with the variable servicer, the CPU load would likely have been low enough that it probably wouldn't even have mattered if the RR was active or not.) Unfortunately, while (I think) that the variable servicer was regarded as a good technical solution, it was then late enough in Project Apollo that it was regarded as safer and possibly cheaper to avoid such drastic changes, and the idea of the variable servicer was eventually dropped.See also:

Note particularly Table 20 (PDF p. 247), which is a list of the LVDC presets. While we don't presently have LVDC flight-program source code for Apollo 14, the listed variables agree largely (or entirely) with those in the Apollo 17 LVDC flight program, so it's possible these values would be mostly okay for Apollo 15-17 as well. While the launch-vehicle operational trajectory documents (as opposed to the spacecraft trajectory documents) do generally include tables of LVDC presettings, this is the only one I'm presently aware of that chooses to tell us the numerical addresses at which the (named) variables being preset actually reside.Allan Klumpp. This was a simulation run by AGC software developer Allan Klumpp. It had some problem which caused it to abort, so the simulation data isn't of much use (because there isn't any!), but it includes various info able pad loads that may be useful.Allan R.

The checklist was still attached to the spacesuit glove when photographed, making for an interesting aesthetic. In the primary link to the document, I've scaled the image quality down considerably to reduce the download size. While there's no degredation of legibility in doing so as far as I can tell, I'm sure there's some loss of fine detail in the gloves.

Stokes, Jr.If you're really paying close, close attention, you may wonder why all of our information on the COLOSSUS page and this page indicates that the same software was used for the Apollo 15-17 CM, namely ARTEMIS 72, and yet the linked document indicates ARTEMIS 72(REV1) instead. Conversely, the Apollo 15 document linked above indicates merely ARTEMIS 72 without a revision. Sounds different, doesn't it? Well, we don't presently have enough information to resolve this puzzling paradox with satisfying certainty. However, Nik Beug points out that the Operational Data Book actually does list ARTEMIS 72 REV 1 for Apollo 16 as well, while Mike Stewart points out that the AGC's memory modules have the same manufacturing dash numbers for Apollo 15 and 16 (indicating that they had the same software loads stored in them). This lends a lot of credence to the notion that all three of these missions really did have the same software load. Plus, you have other support, such as memos like this one. But whether that software version was ARTEMIS 72 or whether it was ARTEMIS 72 REV 1 is still unclear, and the available data allows it to be argued either way.R-713, "Reliability History of the Apollo Guidance Computer" or here, 01/1972, by Eldon C.

The 3 volumes of this document comprise a study that explores using alternate, higher-level programming languages in place of LVDC assembly language. The languages are SPL (Space Programming Language), CLASP (Computer Language for Aerospace Programming), HAL (High-order Assembly Language), and CMS-2 (Compiler Monitor System-2). Of these, HAL looks the most like a modern program language, naïvely speaking, though the report notes that it was the most difficult in which to program. Amusingly also, the language (in spite of its acronym-style name) was actually named by Ed Copps (an AGC developer, not an LVDC developer) for Hal Laning (also of Draper Labs); however the language itself was not developed by the Draper/Instrumentation Labs. The principle significance of the document for us, however, is that the study reveals a lot of detail about the existing LVDC software to which we're not otherwise privy.72-0005, CR-123570, "Flight Program Language Requirements", volume II of III, 03/07/1972, by T.

This fascinating "document" helped in reconstructing Skylark 48 source code from dumps of physical core-rope memory modules. I've quoted "document" because it's not clear if this is a fragment of some other document, or whether it's simply an ad hoc aid somebody created during Skylark development without any notion of it being in any way official. It has neither a title, date, nor any attributed authorship. I've assigned it to 1975 and to the Instrumentation Lab simply because the Apollo-Soyuz Test Project (ASTP) mission was the last flight of the Skylark software ... or indeed any other Apollo-type AGC mission.NASA.

This is actually a book in the NASA History Series, so it isn't as technical, but is full of all sorts of contextual detail that is missing from the technical documents.LNY-83, "At touchdown (P66) N63 gave ...

Charlie Leist. This is a short Gemini OBC snippet of code created upon request by original Gemini OBC developer Charlie Leist. Further comments are in separate memos, "Some thoughts on creating sample Gemini OBC code" and "More thoughts on creating sample Gemini OBC code".Charlie Leist. This short memo by original Gemini OBC developer Charlie Leist relates to a sample OBC code snippet he created for me, given then-absence (and now-absence, for that matter) of any true listings of contemporary OBC code. You can find the code snippet elsewhere in the library, under the title "Sample Gemini OBC Code Snippet".Pat Mooney, Charlie Leist. This is not a contemporary document, but is rather a modern document (2012) written by Pat Mooney (Gemini Programming Manager) and Charlie Leist (Re-Entry and Touchdown Predict Programmer) in which they try to capture how the software-development process worked. There is some overlap with other documents, of course, but where there is, there is often more detail. For example, there is not merely a list of developers, but a breakdown of their actual responsibilities.Kent Carter. James E. Dobson, Rena J. Mosteirin. This is a book by poets, deriving poetry from the Apollo 11 AGC source code. In introducing the material, I seem to recall they remark that we — the Virtual AGC Project — got the AGC source code by OCR'ing the original program listing ... a canard! We had to type in every little smeckle of source code with our own fat little fingers! So don't you go around repeating this calumny. But still, they're poets and not journalists; and besides, for all I know, I may unintentionally be telling whoppers about them, just in this tiny comment. In other words, if that's the worst problem they have, they must be doing pretty well. If you like the book, go out and buy a hardcopy.Rev 1.0, "Saturn V Step-by-Step", 10/01/2024, by Mark Schulman. The author of the document tells me that he'd be pleased to have feedback so that the document can be improved or corrected. Please send such feedback directly to Mark at the email address given in the document, and not to us here at Virtual AGC. I'd also note that newer versions of the document, if any, would likely be available at that email address before they become available to us here.
