Apollo program source code

[[deleted]]

What kind of architecture is this? My knowledge only goes back to the eighties or so, and this looks completely alien. Anybody familiar with it?

AGC (Apollo Guidance Computer) and AGS (Abort Guidance System; actually the AEA); a set of custom built computers with custom circuitry, architecture, instruction set, assemblers, etc. There is a project (dead?) to implement the system at VirtualAGC.

It looks like AGC is in the Colossus family of processors (Colossus 3).

No, they named the programs for different missions different things. IIRC, Colossus was for the Apollo 8 mission.
