REPORT

Block I
Apollo Guidance Computer (AGC)
How to build one in your basement

Material developed and provided by John Pultorak who is kind enough to put 
these files into the public domain with no restrictions on their use.

Abstract

This report describes my successful 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.

I built it in my basement. It took me 4 years.

If you like, you can build one too. It will take you less time, and yours 
will be better than mine.
