Project to build a working reproduction of the 1964 prototype for the Block I Apollo Guidance Computer. The AGC is the flight computer for the Apollo moon landings, with one unit in the command module and one in the LEM.

Sounds like a great weekend project, but why build an AGC?

Early computers are interesting. Because they’re simple, you can (if you like) actually understand the entire computer, from hardware to software.

The AGC is the most interesting early computer because: it flew the first men to the moon and has interesting architectural features.

So there you have it. Please submit photo’s of your home-made AGC to the team here at Forever Geek in the usual manner.
