Source Code
These source-code files are part of a reconstructed copy of Luminary 96, the
original release of the Apollo 11 Lunar Module (LM) Apollo Guidance Computer
(AGC) software.
The reconstruction began with reconstructed source code for Luminary 97. Changes between revisions 96 and 97 were backed out, as described by anomal report LNY-59. transcribed from a digitized copy of that program. 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 96 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. |

038376,000004: ## Purpose: A section of Luminary revision 96.
038377,000005: ## It is part of the reconstructed source code for the
038378,000006: ## original release of the flight software for the Lunar
038379,000007: ## Module's (LM) Apollo Guidance Computer (AGC) for Apollo 11.
038380,000008: ## The code has been recreated from a previously reconstructed
038381,000009: ## copy of Luminary 97 by undoing changes described in anomaly
038382,000010: ## report LNY-59. The code has been adapted such that the
038383,000011: ## resulting bugger words exactly match those specified for
038384,000012: ## Luminary 96 in NASA drawing 2021152D, which gives relatively
038385,000013: ## high confidence that the reconstruction is correct.
