Z80 SBC – Zapple

This is a Z80 single board computer that I made some years ago, After reading this excellent book “Build Your Own Z80 Computer Book” by Steve Ciarcia.

I have made a  “Zapple like Monitor” it’s a work in progress.

It’s built on a breadboard at the moment. I’ll Design a PCB at some time in the future and expand the RAM to 64k and ROM Monitor to 32k.








System features:

CPU: Z80 running at about 1.997Mhz
ROM: 2K Monitor
SERIAL: Intel8251A Uart
