Incidentally, what type are the actual ROMs in that board -- are they
27C64s like the M512? I guess the speed grade is probably not all that
critical given how slow the clocks seem to be going on these things :-}
Annoyingly, a quick rummage through my parts collection didn't turn up
any 27C64s. I see Farnell do still sell them, but they seem to be
remarkably expensive. Does anybody happen to have a stash of those
chips that they'd be prepared to part with?
