    Strange beast indeed, DIN5, no poka-yoke on the SCSI and that weird socket. It just found its home at the museum!

    “Weird socket” being Socket 2? It may be unusual but it’s a lot more useful than a LIF socket 🙂

    Hi, I recently acquired this exact motherboard from a scrapper and all of the ICs were missing including GAL.
    The other ones are not that hard to get a hold of, but I have a problem with the GAL image. Could you guys be of any help? I’ve heard that the GALs are write-only and can not be read.
    Thanks!

    I fear that I don’t have any idea how to read out the missing GAL… maybe someone else?

    The ability to read a GAL seems to depend on the type of GAL and if it’s protected or not.

    Found a thread that seems a bit interesting. Unfortunately the links are broken, but still.
