WinCMOC v0.6 is here! So many new features, I cant remember them all. Please uninstall old versions before installing.

This is a port of the CMOC compiler (written by Pierre Sarrazin) to Windows. Currently CMOC does not support linking, so, I've written front end tools which edit CMOC's output so that it can be assembled and linked via LWTOOL's.

A simple C editor in included which makes it easy to compile/build and run the xroar emulator.

Please visit the CMOC website:


LWTools - Portable tools for the Motorola 6809/6309

mcpp - A Portable C Preprocessor

Artistic Style - Automatic Source Formatter

XRoar - Dragon & CoCo emulator

CMOC - 6809 cross-compiler for a small C-like language
