7400 Series IC Nibbler 4-Bit CPU – PCB Version!

and want to build your own CPU, check out the updated Nibbler, built with multiple 7400 series ICs (74HC32, 74HC74, 74HC163, 74HC125, 74HC173, 74HC181, 74HC244, & 74HC377) and other components.

Nibbler is a 4 bit CPU built from standard 7400 series logic chips. Despite using only 17 chips, it can do some interesting tricks. It was designed by Steve Chamberlin (of Big Mess o’ Wires Fame) and was originally constructed using the wire-wrap process. This is an updated design that uses a printed circuit board and some component substitutions.
