RE: CineMenu update

G'day Paul (and folks),

If BB used switches on the control panel and didn't have such
specialized sound and color converter boards, I'd push for its inclusion
into the multigame. But I think that even if you do manage to overcome
the banking problem, you'll be stymied by these other obstacles. Sure a
Cine->Atari translator for the monitor might get you around BB's color
converter board, but what about the sound card? Doesn't it also handle
D/A for the spinner? Also the number of wiring mods on the mother board
(not the daughter board) are daunting.

However, with this said, I do agree with Paul's OTOH comment. If you
did move banking up to the daughter board (and use BB's addressing
scheme), then you'd have additional flexibility with motherboards from
earlier games. I'm assuming J10 would effectively be brought up onto a
multigame board. Is someone planning to create a multigame PCB like
Clay's Sega that would piggyback on the motherboard like BB's daughter
card already does? (Looks like I must have missed that part of the
discussion...)

ps - I still think the Cine universal sound card is a better place for
everyone's efforts. But who am I to say...I'm essentially whining
instead of doing, eh?
