I put the C02 project on GitHub. Due to non-vcs patches to the compiler, I had to create a separate branch with a version that will compile programs in the vcs directory. This branch will eventually be merged back in.
The compiler can be built using gcc and Makefile or using the Pelles C compiler for Windows and the c02.ppj file.
To compile a .c02 program, cd to the vcs directy and issue the command "c02 filename" on Windows or "../c02 filename" in Linux, etc... where filename does not include the .c02 extension.
