dzOS download | SourceForge.net

dzOS is a single-user single-task ROM-based operating system (OS) for my 8-bit homebrew computer dastaZ80, which runs on a Zilog Z80 processor.

It is influenced by ideas and paradigms coming from Digital Research’s CP/M, but also from 8-bit computers of the 80s era.

Features

Divided into three parts: BIOS, Kernel and Command-Line Interface (CLI)
User Modifiable Operating System: during boot, the ROM is copied to RAM and the paged out, giving the user total freedom to modify the OS.
Use of jumpblocks for Kernel and BIOS subroutines allows easy modifications by just changing 2 bytes to a new address
Written in Z80 assembly language
Support for TMS9918A VDP, AY-3-8912 PSG, Zilog SIO/2, SD card, Floppy Disk Drive
