A 4 Bit Computer, built from TTL chips

June 10, 2010 | electronics | By: Mark VandeWettering

I am always on the lookout for people who build interesting computers from scratch. Here’s another nifty one: a 4 bit CPU called the Duo 128 Elite by Jack Eisenmann. It’s a pretty obscure little architecture, but is cool enough to play pong on a 8×8 LED display.

Very cool, especially for a 4-bit machine.

Mark, I’m glad I found your site. I found the detail on your “About Myself” very interesting.
