Source Code
|
These source-code files are part of a reconstructed copy of LUM69 Revision 2, the
flown Apollo 10 Lunar Module (LM) Apollo Guidance Computer (AGC) software.
The reconstruction began with source code of Luminary 69 revision 0 previously
transcribed from a digitized copy of that program. The code was then updated
by back-porting the R-2 lunar potential model from previously-transcribed source
code of Luminary 99. These required changes were described in the original
Luminary memos 75 and 78. The reconstructed code 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 069 printout,
although the added code would likely have changed page numbers for a real LUM69
Revision 2 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.

007496,000004: ## Purpose: A section of LUM69 revision 2.
007497,000005: ## It is part of the reconstructed source code for the flown
007498,000006: ## version of the flight software for the Lunar Module's (LM)
007499,000007: ## Apollo Guidance Computer (AGC) for Apollo 10. The code has
007500,000008: ## been recreated from a copy of Luminary revsion 069, using
007501,000009: ## changes present in Luminary 099 which were described in
007502,000010: ## Luminary memos 75 and 78. The code has been adapted such
007503,000011: ## that the resulting bugger words exactly match those specified
007504,000012: ## for LUM69 revision 2 in NASA drawing 2021152B, which gives
007505,000013: ## relatively high confidence that the reconstruction is correct.
