[Carsten] spent over a year developing a small CPU system, implementing his own minimalist instruction set entirely in TTL logic. The system uses a serial terminal interface for all I/O, hence the ...

The registers inside the CPU, the machine code instruction set, and the ways in which the instructions interact with the registers and status flags are all intertwined. As you may recall, one of my ...

This proposed instruction set is intended to run on both virtual and physical incarnations of the 4-Bit HRRG Computer As you may recall, my chum Chewy is interested in designing and building a 4-bit ...
