If you were building one now, you could arrange the memory slightly
differently and use fewer ICs. Or if you are using a GC you could omit the
memory entirely.
One of the things I have half a mind to do is an interface that could be
a TrumpCard or a SuperQBoard, should be fairly straight forward.
64K ROM with both SuperQ & TC roms, CPLD with the decode and select
logic in it, WD1770/1772 and a 1MB static RAM chip, though obviously
some of that would never be used. I guess the only component that would
be hardish to get hold of would be the WD177x.
Cheers.
Phill.
