Are you sure it's a PCI board? If it's from '93 it's to old to be a PCI
board, as it was in late '95 that Apple switched from NuBus to PCI slots.

I suspect you're right, no sign of a x86 CPU? It doesn't sound like ones on

Well, Apple has had a habit of putting parts of their systems on other
boards. I think what you've got here is the Video and Audio portion of a
68k based Mac. Taking a quick look at what was shipping in '93 I'd guess that it's from a Centris
or a Quadra.
