The Apollo Guidance Computer (AGC) played a critical role in the Moon landings. One of the first computers to use integrated circuits, the compact AGC provided guidance, navigation, and control onboard the spacecraft. This talk explains how we repaired an AGC (including its ferrite core memory), got it running, and ran the original Moon landing software on it. I'll also discuss the AGC's innovations in software engineering, user interfaces, interpreters, realtime computing, and multitasking, along with its performance mining Bitcoins.
