  Look at the chip number TMS 4532-20, That's almost certainly a memory chip.
Probably something like 32K or 8K x 4. 44 chips would be 11 8 bit words or 
about 88K x 8 bits.  Quite reasonable amount for a old 34....
   I have seen a bunch of 1. Non-DEC memory cards, this may be one.  2. DEC
cards with out the correct part number terry is refering to.  (For a variety
of reasons, and sometimes I wasn't even involved 8-} .) 3. DEC cards which
the only existing (still) number is hidden or imbedded in the screening or
soldermask of the circuit.  Not many dec cards, especially old dec memory cards
had sockets for adding more memory.  Unless it said DEC in big red letters,
I'd suspect it was a aftermarket.
