I've got a NEC Powermate SX board inside a NEC Powermate 1 case (works great!) and the Powermate SX has a curious "extended" ISA slot that I can't seem to find much information about. I gather it's for a proprietary memory card, but I can't seem to find any information as to what I might start looking for.
If anyone has any clue, I would certainly appreciate a heads-up.
