    Default TMS 1000 vintage 4-bit

    Hi

    Who has dumped the ram from a TMS 1000 series using the 'test mode' ?

    Thanks

    Unfortunately, I haven't done much with a TMS 1000 at all--other than read the manual.

    Given the fact that the TMS1000 is ancient PMOS (logic level issues) and doesn't contain that many instructions in its program ROM, it seems to be easier to simply reverse-engineer the functionality of the thing.

    I've got a couple rattling around in my hellbox, but I've never been interested in reading out the contents for what appears to be nothing more (in their cases) a relatively simple programmable timer.

    Do you mean "dumped the ROM"? Is that even possible? I don't see a procedure in the 1976 TMS 1000 Series Data Manual.
