Bill Kotaska's Busicom 141-PF Replica

Are you a computer engineering student and can’t find a doable project for your design subject? Or are you a microprocessor L33t wannabe who likes to tinker with the good stuff and not the Quad/Octo cores available? Then read on!

Scouring Digg yet again for random goodness, this post caught my eye! It’s about Bill Kotaska’s Busicom 141-PF replica, a calculator/printer powered by an ancient Intel 4004 microprocessor! Now if I only saw this 2 years back…

Here’s one of the schematics Bill used to create the CPU and memory module. You can find the rest of the schematics on his Busicom page.

Get to work engineers! :D
