Source Code
|
These source-code files are part of a reconstructed copy of LM131 revision 1,
the final release of the Apollo 13 Lunar Module (LM) Apollo Guidance Computer
(AGC) software.
The source reconstruction began with source code of Luminary 131 previously
transcribed from a digitized copy of that program. A dump of the flight spare
core rope memory module B5, part number 2010802-171, serial number RAY 411,
was obtained. This module is the only module different between Luminary 131
and LM131 revision 1. The dump was disassembled and all changes were incorporated
into these source files. Note that page numbers in the reconstructed code match
those on the Luminary 131 printout, although the changed code would likely have
changed page numbers for a real LM131 revision 1 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.

009976,000004: ## Purpose: A section of LM131 revision 1.
009977,000005: ## It is part of the reconstructed source code for the final
009978,000006: ## release of the flight software for the Lunar Module's (LM)
009979,000007: ## Apollo Guidance Computer (AGC) for Apollo 13. The code has
009980,000008: ## been reconstructed from a listing of Luminary 131 and a dump
009981,000009: ## of a core rope memory module B5, part number 2010802-171,
009982,000010: ## which is the only module different between LM131 revision 1
009983,000011: ## and Luminary 131. The executable generated from this source
009984,000012: ## has been verified against the module dump, so while the names,
009985,000013: ## comments, and ordering may not be exactly correct, the
009986,000014: ## resulting binary is.
