CPM-Emulator

Yet another Z80 Computer with CP/M capabilities (no BIOS, emulated BDOS, executed CP/M)

A C++ CP/M machine emulator with embedded Z80 by Sainz de Baranda y Goñi, Manuel manuel@zxe.io. BDOS functions are C++ coded. BIOS functions are not provided (until now).

Tested with ZEXDOC from http://mdfs.net/Software/Z80/Exerciser/

Installation

Copy localy the CCP-DR.64K file from https://github.com/MockbaTheBorg/RunCPM/tree/master/CCP or another CCP version and change loading & running parameters accordingly in source code (main.cpp#L45 )

Create dir /A, /B, etc. as you need. They will simulate local CP/M disks. Only files with 8+3 filename will be seenable. Try DIR a:.

You may also use GlassTTY: TrueType VT220 font.

Usage example
