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

I have a series of kits for sale for a simple Z80 microcomputer that can be assembled by hobbyists or students with average soldering skills. The kits progress from a bare-bones system board up to a system with a disk interface capable of running the CP/M operating system.

This computer processor was made of 7400 series ICs, and can connect to the Z80 socket on the CPUville Z80 computer kit system.

These are pages explaining the basic elements of computer electronics

If you have a homebuilt CPU project you would like to add to the webring, contact David Brooks, designer of the Simplex-III homebrew computer, here, mentioning your page's URL. It will then be added to the list. You will also need to copy this code fragment into your page.
