Source Code
These source-code files are part of a reconstructed copy of Artemis 071, the
first release of the Apollo 15 through 17 Command Module (CM) Apollo Guidance
Computer (AGC) software.
The reconstruction began with source code of Artemis 072 previously transcribed from a digitized copy of that program. The code was then updated by undoing changes between the two versions. The reconstruction was verified by matching memory-bank checksums to those listed in drawing 2021154-. Note that page numbers in the reconstructed code match those on the Artemis 072 printout, although the changed code would likely have changed page numbers for a real Artemis 071 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. |
