The Whizz80 computer project is an open-source, home brew, retro computer based on the old 8-bit Z80 CPU by Zilog from the late 1970s. The goal is to have a working stand alone computer, both hardware and software using easily available components and materials that anyone could build.
This project is currently under heavy development.
Everything that you want to know about the Whizz80 is obtained from within this website, or follow along the project status via the build log.
