OK, now it gets weird. I have used multiple keyboards, mice and ADB
cables so they are not it. I have taken the memory card out so it is
not that, checked for any loose chips.

 It is still happening with the reproducible results below-

Results with CFFA Card in any slot:
-turn on power, boots fine, apple-ctrl-reset at any time after initial
power up, crash with "Unclaimed Sound Interrupt" error.

Results with Focus Card in any slot:
-turn on power, freezes on initial "Apple IIgs" boot screen, apple-
ctrl-esc (to get to control panel) results in crash with "Unclaimed
Sound Interrupt" error.

Both these a conditions are reproducible every time.

Any other ideas?
