Source Code
|
These source-code files are part of a reconstructed copy of Luminary 97, the
original release 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 memos 83 and 85, using asterisks
indicating changed lines in the listing as a guide. The reconstruction was
verified by matching memory-bank checksums to those listed in drawing 2021152D.
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 97 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.

006074,000003: ## Filename: INTERRUPT_LEAD_INS.agc
006075,000004: ## Purpose: A section of Luminary revision 97.
006076,000005: ## It is part of the reconstructed source code for the
006077,000006: ## original release of the flight software for the Lunar
006078,000007: ## Module's (LM) Apollo Guidance Computer (AGC) for Apollo 11.
006079,000008: ## The code has been recreated from a copy of Luminary 99
006080,000009: ## revision 001, using asterisks indicating changed lines in
006081,000010: ## the listing and Luminary Memos #83 and #85, which list
006082,000011: ## changes between Luminary 97 and 98, and 98 and 99. The
006083,000012: ## code has been adapted such that the resulting bugger words
006084,000013: ## exactly match those specified for Luminary 97 in NASA drawing
006085,000014: ## 2021152D, which gives relatively high confidence that the
006086,000015: ## reconstruction is correct.
