This is likely not really the right place to ask this, but nobody else in
other groups has a clue about a 16bit ISA board I have. It is as follows:
16bit ISA board for IBM compatiblle
16mhz MC68020RC16B and MC68881RC16A processors
16 30 pin memory modules soldered directly to the circuit board
each module contains 9 41256-120 RAM chips (NEC 8608E621)
1 DB-9 and 1 DB-25 connector (both male) on the rear cover plate
Markings: "DSI-780" on the front, and "Rev B Copyright 1986
Definicon" on the rear
There is also an empty socket, the same size as the 68020 socket.
I aquired this board from a pile of misc. circuit boards that was being
tossed out a couple of years ago, and have not been able to find out any
information on it. Any info at all would be most helpful. To me, it appears
to be some kind of hardware emulator for an Apple or Mac. I know in the late
80's there were a number of Apple II emulator boards for the PC running
around, as I recall seeing them for sale in the Radio Shack catalogs of the
period. Any help would be greatly appreciated.
