Right. I've not traced out the schematic (to get the wiring of the 26 pin 
cable), and don't intend doing so anytime soon, but it's hardly going to 
overtax me if I need to use it...

Possibly. It doesn't look like a disk controller, there's no 34 pin

Yes, I think I have one of their S100 boards somewhere, but it would take 
some finding....
