Z80 v2

I’m not sure but still soon to say that this year will be the year of the Z80. I’ve been working on a new version of the Z80 computer that I’ve built last year. The new version that I have in mind will have a lot of improvements over the previous one, and possibly a printed circuit board (PCB) to make it more professional.

Improvements that I have in mind:

I’m currently working on implementing a CP/M for my small Z80 CPU. As a reminder, this involves a single Z80 CPU connected to a Raspberry Pi, with the latter emulating RAM, ROM, and IO devices.

I spent this weekend diving into the workings of CP/M disks. While there is a Unix tool available to create CP/M disk images , I’ve decided to create my own version using Python.

I have a long history with computers, starting with a Sinclair Zx81 that I still own, followed by other models and others that I wished for, as time went by.

A while back, I found an old box with some old processors, x386, x486, a few Pentiums first generation and two Zilog Z80. Then I got a kind of retro-feeling in my mind and I watched some YouTube videos about them. One of them was the classic nop-test, I had fun with this for a whole afternoon.
