It was meant to plug in in a standard PC, that thing run some control
application in semiconductor production equipment..running his own
VAXELN Subssystem. (never seen that, the friend who gave me that card
told about it).
The PC had a 486 CPZ and an AHA1542 in it. I think it must have had some
briging software for booting an disk access.
