Source Code

These source-code files are part of a reconstructed copy of Sunrise 45, the penultimate release of the Block I 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 1003133-18, 1003133-19, and 1003133-20. Corresponding portions of code have been copied from Solarium 55 where applicable. Extensive use was also made of the AGC Information Series documents, which were specifically written about the Sunrise software.

Since only binary dumps (rather than listings) of Sunrise 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.
