That part number is probably an OEM number or batch number. Old IBM
computers were stuffed full of logic chips whose functions were
commonplace but whose part numbers bore no resemblance to what you'd
see in a databook. They appeared to be trying to corner the market
for servicing their machines as well as selling them, no doubt for a
hefty fee. Such might be the case for the equpiment from which that
part came.

      There probably isn't a manufacturer in the world that has data
on all its obsolete parts. Unfortunately, hobbyist's needs and
concerns don't seem to be part of the game. Equipment these days is
probably meant (by the manufacturers) to be thrown out the moment it
stops working and not have juicy parts ratted out it.
