    Default What is this (8088 FEP-2/3?) board?

    Does anyone know what exactly this board is?

    It looks like a 16-bit ISA board, seems to have communication (SD and RD) indicator lights, has a ceramic Fujitsu 8088-2 CPU, and the ROM has the label "FEP-2/3".

    There is a bit more discussion of it here: https://winworldpc.com/winboards/vie...hp?f=10&t=9760

    Fujitsu uses the term "FEP" for front-end processors for their big servers. (e.g. PRIMERGY and PRIMEPOWER). That would appear to agree with the contents of this card, though I don't know exactly what system it came from.

    My guess is that it is an ethernet card. It would connect to one of those
    ethernet modules that clamped onto the thick ethernet cables.

    I don't think so, Dwight.

    Consider what's on the board--you have a NEC D27001 MPSC, a TI SN75118 dual differential reciver/transmitter (RS422) and a TDK ZJY51R3 line filter. And then there's the 9.8304MHz XCO--which is a commonly used baud rate reference.

    This thing screams RS422 data acquisition/process control to me. The Fujitsu QFP is an 8088 support device.
