    I once tried to make a ridiculous multi-processor computer, which took advantage of the TMS-9900’s weird clocking to allow it to run faster CPUs in between slower clock cycles. The 9900 has a four phase clock and a maximum speed of 3mhz. I wasn’t skilled enough to pull it off, but it’s still a really interesting idea.

      It would be interesting to play with multi processors, but that is beyond me. Here, I’m trying to follow Ben Eater’s 6502 project again from the beginning, but I want to see if I can follow along with multiple processors in assembly.

      I also have a copy of the book Threaded Interpreted Languages about building FORTH like languages from scratch. That is written for the Z80.

      I also have the 68k book, and The Art of Electronics 2nd edition with several sections on the 6809.

      I’ve actually got the glue and peripherals to get pretty complex, but as is the case with most of these type projects, the computational hardware is easier than a display. That is the bigger payoff, but often ruins the retro part.
