well, it looks like the sound part of it is still up in the air, so
what about a board with just the bank switched ROM, 4 player input
mux, level converters for a WG monitor, with adr/data buffering
and a couple of 22V10's wired up for io and adr decoding, then a
big wire wrap area to prototype the sound hardware? Bring out the
adr/data and strobes to vias so they're easy to get to. That way,
if you didn't want to mess with the sound at all you could bank
switch the existing sound cards with a single wire over to this
card which would replace the EPROM board.
