The Z80 is an 8-bit microprocessor made by Zilog. The CPU came on the market around July 1976.

The Zilog Z80 was a software-compatible extension and enhancement of the Intel 8080, and like the 8080 targeted embedded systems.

However, it became one of the most widely used CPUs in desktop and home computers from 1970s to the mid-1980s.

What I am going to do….. Well being a little crazy – why not build an Z80 based computer. While I wait on some parts for other projects. I have a few Z80 processors on hand.

I will take some steps and go though the process of building a basic – CPU RAM/ROM card with a bus.

Part of me would like to turn it into a TRS-80 clone. Let’s see where this goes.
