This site is dedicated to sales of an educational 8-bit computer kit which uses the Z80 for its central processing unit (CPU). This microcomputer kit is based on the wire-wrap hobbyist system I describe in my main web site, which in turn is based on designs made popular by Steve Ciarcia in his book Build Your Own Z80 Computer, Byte Books, 1981. I created this kit in response to requests by site visitors for an easier way to build a Z80-based computer. The best way to get familiar with the kit for sale here is to download and read the kit instructions. If you still have questions, please email me.  --Best wishes, Donn Stewart.

Display Board

Price: $16.50

This is the bare circuit board from the bus display kit. It is for hobbyists who already have many of the components that are included with the kit. You can save some money if you use components you already have. The computer kit instructions has a complete parts list for the display kit on page 63 that you can refer to. I buy the parts from Jameco Electronics, and you can buy any parts you might be missing from them. If you have any questions about the exact parts you need, contact me and I will help you pick the correct parts.
