This catergory provides general information about the Mini80 Z80 based CPM 2.2 computer project.

Mini80 Overview

This article introduces the Min80 project. The Mini80 project is a Zilog Z80 based CPM 2.2 computer. All the computer peripherals are emulated using a Parallax Propeller chip. The Propeller chip is used to provide a boot loader for the Z80 CPU, four CPM disk drives (uses SD card), 3 COM ports (2 are 4 wire, 1 is 2 Wire) and read access to the root folder of the files stored on the SD card. The two main constraints for the project where; a real Z80 CPU (no emulation), and keep the project as simple as possible. The first prototype uses the PropTerm project as the system terminal.
