This is the source of the sound/music for the game.

Yep. Two layer, pretty simple. Main problem there is that it's physically
a pretty large PCB. Just be kinda expensive to make.

>3 . What all does the tempest->mh adapter do (once again, no schematics yet)

It's "active" function is to correct the "bowing" of the display on a Wells
Gardner monitor. It might have some passive function to re-route some I/O
lines too-- I doubt it though. (Don't recall off the top of my head.)

I'm going to make some display correctors (they work with Star Wars/Major
Havoc), but the Sega Multigame has been eating all my time...
