This is a homemade cpu. Or something.
There is currently one CPU architecture, the 16-bit "proc16a" and two designs that implement this architecture (proc16a1 and proc16a2). Different cpu architectures that I may add in the future would be named "proc16b" etc.
Documentation is in the doc folder. Schematics to be used with Digital are in the schematics folder. Assembler and emulator are in the tools folder.
A high-level language (or even full C support) may be added.
