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.

Power connector

Price: $1.70

This is a simple plug with leads that fits into the power-in jack on the computer kit board. It is for hobbyists that already have a power supply capable of at least 2000 mA current at +5V DC regulated (a 10-watt supply) for running the computer kit and display.
