Source Code

These source-code files are part of a reconstructed copy of Sundial E, the final release of the Block II Command Module (CM) Apollo Guidance Computer (AGC) system test software.

They have been created via disassembly of binary dumps of original core rope memory modules, part numbers 2003053-121, 2003053-151, and 2003972-211, belonging to the MIT Museum.

Since only binary dumps (rather than listings) of Sundial are available as source material, all comments and labels are approximate. They have been taken from other AGC programs where possible, or, in some places, written from scratch to match what we believe would have been in the original listing.
