If you're lucky the host interface on that sort of board is SASI (SCSI is
possible, but not common). Otherwise it might be a custom interface, but
it'll probably be 8 data lines, some register select lines, etc.

But of course the problem is that many machines didn't use that sort of
adapter board.
