The Quad pokey board is for the sound effects.

I don't think it would be too hard to dupe. if I remember right, there are
only 4 pokey chips on it and nothing else (I'll double check tonight)

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

The adapter allows a mh bs to plug directly into a tempest. It also moves
the x & y adjustment pots to the adapter (the pots on the main pcb are
disabled). I think it might also compensate for pincushioning on a wells
monitor.
You can just wire up a new harness and just forget about the adapter and
everything should work ok (the dedicated hm had no adapter)
