Homebrew Relay Computer

Following on from yesterday’s homebrew CPU link, here’s another stunning homebrew machine. But none of that fancy new 74 series stuff for Harry Porter, of Portland State University’s Computer Science Department - oh, no - he’s built his machine from 415 four-pole double throw relays.

Follow the 'more information' link and check out the movies and MP3 - they are worth it just for the sound of the machine in action.

By the way, here's a nice simulation of various logic gates, adders, flipflops and multiplexers built from relays. Click on the inputs on the left to animate the circuits.

Now where did I put that old box of Audions...
