Anyone who is looking for something to run it on could take a look at Block I Apollo Guidance Computer (AGC): How to build one in your basement [1]. The build took one guy four years and a lot of wire-wrap. A fascinating and quite awe-inspiring piece of work.
that guy deserves a medal. 4 years of work and documentation and he gives it to the world. the documentation is pretty good with some incredible pictures and diagrams. now granted i'm not an electrical engineer so i don't know if it is accurate.
