    Yeah, I tried but don't think anyone's willing to dust off a databook that old to email me the pinout......

    ..crazy thing is I know there's at least 500+ systems with these cards still in use !

    Best to try to contact Altera's support and ask for the datasheet.

    I appreciate the quick reply.

    Any chance you have the pinout ?

    It's tied into an Intel 8344AH on the card and while I could reverse engineer it, having the pinout would kinda help.

    Google didn't seem to know what it was !

    Ouch... This guy was obsoleted in 1996.

    It's a apparently a simple EPLD/PAL. I found some apparent devices available from "Grey Market" sources.. But you would still need to know how it was programmed.

    If it's an ISA bus card, it was probably used as an address decoder..

    If this is something that must be maintained for any period of time, I would highly recommend sending the entire system to someone for reverse engineering.. Because likely most of the components in the system are now obsolete.
