Source Code
These source-code files are part of a reconstructed copy of Luminary 98, a
development version of the Apollo 11 Lunar Module (LM) Apollo Guidance Computer
(AGC) software.
The reconstruction began with source code of Luminary 99 revision 1 previously transcribed from a digitized copy of that program. The code was then updated by undoing changes described in original Luminary memo 85, using asterisks indicating changed lines in the listing as a guide. While no listing of this version is known to exist, nor are the memory-bank checksums available, the reconstruction is believed to be correct because it was an an intermediate step in reconstructing Luminary 97 whose reconstruction was verified by matching memory-bank checksums to those listed in drawing 2021152G. Note that page numbers in the reconstructed code match those on the Luminary 099 revision 001 printout, although the added code would likely have changed page numbers for a real Luminary 98 listing. 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. |
