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 [email protected]. 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

Start emulator & load CP/M (as default)

$ cpm

Start emulator, load & run zexdoc.com file

$ cpm zexdoc.com

cpm-emulator's Issues

Update the Z80 core

Hello Marc,

I've forked your project to update the Z80 core. The version you are using is very old and I will release the v0.2 before New Year.

Please, take a look at it: https://github.com/redcode/CPM-Emulator

Now, Z80 and Zeta are git submodules and you can build the project using CMake.

Try it:

git clone --recursive https://github.com/redcode/CPM-Emulator.git
cd CPM-Emulator
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release
cmake --build .

If it's OK, I would like to create a PR.
