Identify old Fairchild component

    Going through old home inventory, came across this part:
    Fairchild (logo)
    p/n 931159
    Date code 7123
    24-pin ceramic hermetic DIP
    No other markings top or bottom

    Any digital geezers out there recognize this? My guess is a (possibly custom-programmed) bipolar PROM, but the part number doesn't match their pattern.

    Thanks
