I have a Unisys 486 computer. It's a SX-25, with a DX-50 in it also.
It's mfg date is 10/92, and style number is SG-3102-425. It's "plateau"
is
labelled Evaluation Unit A. That would explain the XXXX in the FCC ID
field...
On the motherboard itself, it has a sticker with...
43611896-000
PW300 486SX/25
9240 AVEX
Sounds like a 486SX/25 system upgraded to a DX2/50 with an OverDrive chip.
...while near the 30-pin memory, printed on the board
is...
UNISYS
PW2 300/486
PWBA 43188028-000
Does anyone know where I can find out what the jumpers do on this board? Or
other specs for it? I though I heard someone mention dual processor WRT this
board, but I doubt it. There is also a smaller LIF socket next to the 2 LIF
processor sockets. IIRC, that is for a 487 math co-processor...
I doubt that its for a 487... I almost wonder if this was some kind of
386/486 board.
