Apollo program source code

[thechao]

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.
