The Jim Austin Computer Collection

MITS altair 8080

This is largely expanded MITS altair 8800 machine. Basically its a classic home computer that can be programmed off switches at the front or via a teletype unit. This joined the collection in Oct 2009, from a collector in Cardiff. I think it came from Canada, it has 115v power supply. Amazingly well built.
