CPUville is dedicated to the computer electronics hobby. The projects and kits here reflect my interest in basic computer hardware. The computers here are simple, and presented in a way that I hope will make them easy to understand. Here are the main things you will find here:

Z80 computer kit


assembled single-board computer kit

I sell a simple Single-board Z80 computer kit that can be assembled by hobbyists or students with average soldering skills. The kit includes an IDE disk interface and is capable of running the CP/M operating system.

8-bit processor kit


8-bit processor three board stack

This kit is a simple 8-bit computer processor that you can build. It is a challenging project, implemented on three printed circuit boards, for the arithmetic-logic unit, the control logic, and the main board. All details of the processor design and construction are open for study.

Homebuilt CPUs WebRing

Join the ring?

The webring is maintained by Warren Toomey. To join the Homebuilt CPUs ring, drop Warren a line, mentioning your page's URL. He'll then add it to the list. You will need to copy this code fragment into your page (or reference it.)
Note: The ring is chartered for projects that include a home-built CPU. It can emulate a commercial part, that′s OK. But actually using that commercial CPU doesn′t rate. Likewise, the project must have been at least partially built: pure paper designs don′t rate either. It can be built using any technology you like, from relays to FPGAs.
