    Quoted from pincoder:

    What about RAM2? Doesn't system 4 have two RAM chips?
    It would be interesting to map out all the values in the CMOS (and RAM too for that matter). It would be great for debugging their code and learning how it was built. Though the only way to map the RAM though is to put the chips on their own power and keep power to them during a reset/power up cycle and boot an updated edit_cmos ROM. Currently the edit_cmos only maps out the address range of the cmos.

    It would be nice to have a full debugger setup in the machine with an external computer to interrupt and debug right there (like Williams did way back when).

    The rest of what you're asking has already been done several times over via pinmame and via recreated source code, although it is very hard to find.
