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.

This is my version of Grant Searle’s 7-chip Z80 computer that i made on veroboard a few years back a very simple Z80 design.
The purpose of this computer is to create the simplest possible machine with a high speed interface, good amount of RAM and also a good implementation of BASIC.
The design that Grant produced is shown here, and is probably the simplest Z80 circuit that can be done to fulfill what I needed.
Micro UK101

The micro UK101 described here is by Grant Searle effectively the stripped-down “core” of the original UK101, and is no way intended to be the full UK101 implementation. The display and the keyboard circuitry and, instead, used a terminal emulation program (eg HyperTerm for Windows) as the keyboard/display. This has resulted in a very simple circuit which is suitable for use embedded-control applications as well as a fully-functioning computer. I have tried to make as few functional changes as possible to allow old software to work, wherever possible. As a result the BASIC ROM is totally untouched.
