ceda-cemu

An emulator for Sanco 8000, a Z80-based French computer. This time, written in plain old C.

This software is released under the terms of the GNU GPLv3 license.

Build

git submodule init
git submodule update
script/docker script/build release

Run

First, you need a copy of the ROMs inside the rom/ directory:

• BIOS ROM
• character ROM

Optionally (but strongly suggested) you also need:

• CP/M disk (.bin)

Then:

build/release/ceda      # run the emulator
telnet 127.0.0.1 52954  # connect to command line interface

Lore: 52954 is just the decimal version of 0xCEDA.

Emulation can be started/stopped/resumed via the provided command line debugger accessible via the telnet session.

In the command line, type:

• mount <image.bin> to mount the CP/M floppy image (optional);
• continue to start the execution;
• help to get a full list of all supported commands;

To emulate the BOOT key of the original keyboard, press INS.

Development

• to add debug symbols:

script/docker script/build debug

• to compile tests

script/docker script/build test

• to run tests:

build/test/ceda

Script

The script/ directory contains some useful script for development. It is suggested to run them in the docker container by prefixing them with script/docker in order to use the correct version of the dev tools.

• format: clang-format sources
• valgrind: check for memory leaks
