I have an XT-based coprocessor card in my possession now without any
software to drive it. It is a

        ABM Z80 board FAB 5000-1 REV C

A flip through PC Magazine (pg 342 Jan 24 1984) revealed that it is
marketed by

        ABM Computer Systems
        3, Whatney, Irvine
        California 92714
        (714) 859-6531

Quoting from the advertisement

        "ABM's PS-3270 Subsystem uses our intelligent communications
        co-processor (ICP) board featuring a Z80B processor with 64K
        memory, 4 serial portts, a parallel printer port and powerful
        multi-tasking emulation software. ...."

*Anyone can help with schematics or software ?. Thanks in advance.
