Hello,
I am trying to update the firmware in an old BBN BitGraph terminal and
it uses four TMS2564 EPROMs, which from what I have been able to determine
(see here:
http://www.spies.com/~arcade/schematics/ROMref.txt ) are not
compatible with a standard 2764. I suppose that I could make four adapters,
but if I can find the correct parts, that would be better.
Does anyone have four TMS2564-45 (or better) that they would be willing
to part with?
