Source Code
|
These source-code files are part of a reconstructed copy of Luminary 69/2,
the flown, final release of the Apollo 10 Lunar Module (LM) Apollo Guidance Computer (AGC) software.
The reconstruction is based on the source code of Luminary 69 — i.e., the
initial, unflown version, "revision 0" — of which
a contemporary listing was available. The code was then updated by incorporating the
differences between Luminary 69 and Luminary 69/2, known from other contemporary
documentation. The only such difference is the implementation in
Luminary 69/2 of the "R-2 Lunar Potential Model", the source code for which was taken
from program Luminary 99/1 (Apollo 11 LM), of which a contemporary listing was also available.
Finally, the now-reconstructed Luminary 69/2 was then validated by assembling it to
executable form and verifying that its memory banks had the correct checksums,
known from still other contemporary documentation.
Note that page numbers in the reconstructed code match those in the original Luminary 69
program listing, or in the ORBITAL INTEGRATION log section, in Luminary 99/1. Page numbers
would certainly differ somewhat in a contemporary Luminary 69/2 listing.
Moreover, annotations that were not present in the contemporary source code have been added
to the reconstructed code to justify each change in Luminary 69/2 relative to
Luminary 69. Here's a guide to the Apollo documentation referenced in those annotations:
Comments from the original source code are prefixed with a single '#' symbol,
whereas comments added later are prefixed by "##" or "###". Report any errors
noted by creating an
issue report at the Virtual AGC
project's GitHub repository.

047814,000004: ## Purpose: A section of LUM69 revision 2.
047815,000005: ## It is part of the reconstructed source code for the flown
047816,000006: ## version of the flight software for the Lunar Module's (LM)
047817,000007: ## Apollo Guidance Computer (AGC) for Apollo 10. The code has
047818,000008: ## been recreated from a copy of Luminary revsion 069, using
047819,000009: ## changes present in Luminary 099 which were described in
047820,000010: ## Luminary memos 75 and 78. The code has been adapted such
047821,000011: ## that the resulting bugger words exactly match those specified
047822,000012: ## for LUM69 revision 2 in NASA drawing 2021152B, which gives
047823,000013: ## relatively high confidence that the reconstruction is correct.
