Welcome to the Z80-Retro wiki!

This repo provides software and information supporting my Retro Z80 system, which currently consists of three separate cards (with links to OSJWLab schematics):

• Z80 retro computer board
• VGA text video card
• PIO, Keyboard and Sound Card

The hardware design for both cards is open source as is all the code in this repository.

Hardware pages:

• Hardware Overview
• Hardware Jumpers
• I/O Port Map
• Memory Map/Memory Management

Software pages:

• ZLib
• ZIOS
• ZLoader
• CP/M
• Microsoft Basic

Note: The video card includes some programmable GAL devices. The code to be written to these devices are held separately in the vga-video respository.

I've also included some useful links to third party tools I've found useful.
