Next oddball find: A board (about the size of a full-length ISA card) labelled as: "A2000 Prototype Card V1.1", "Interface Megavision / Megalink", "c+p 1988 by SANG Computersysteme GmbH" Bus is 100 pins (50 each side of the board). There's a handful of buffer and PAL chips right by the bus connector, but otherwise it's a blank prototype card. There's a ten pin IDC board-mounted socket in the bottom-right corner. Any ideas what / where / why / when? :-) cheers, Jules
