This is a Z80 single board computer that I made some years ago, After reading this excellent book \u201cBuild Your Own Z80 Computer Book\u201d by Steve Ciarcia.<\/p>\n
I have made a\u00a0 \u201cZapple like Monitor\u201d it\u2019s a work in progress.<\/p>\n
It\u2019s built on a breadboard at the moment. I\u2019ll Design a PCB at some time in the future and expand the RAM to 64k and ROM Monitor to 32k.<\/p>\n
