Welcome to the Z80-Retro wiki!

This repo provides software and information supporting my Z80 retro computer board and the separate VGA text video 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
• 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.
