        The 60-pin header is a giveaway. That's either the 4MB or 8MB memory expander for the UniSite series (with the original controller board -- it won't work on the later production units).

        Take a close look at the label on the PAL. It should have a Data I/O part number on it. Tell me what that number is, and I can tell you which memory size it will accommodate.

        It'll use standard 1Mx9 PARITY SIMMs. You MUST use parity, and (in most cases) they must be the nine-chip type. Data I/O expander boards had trouble with the three-chip type SIMMs.
