Looks like date codes on ICs are 79-82.  Would they have made a core board in 82?
Maybe late builds for repair/replacement in older machines?

Honestly I dont know for sure, but 32 is too much for this era board.  It
could be only 8K but it looks too new.  What year did univac becime sperry
univac?  The board is only as old as that date, or less.  Then if you can
look at the silkscreen on the ttl chips for dates.

So each plane is known to be 8k? ... that was standard or typical?

Web hits on this are thin.
Anyone know what Univac machine this is from and its capacity?
I suppose count of the wires H x L  = # of bits of storage, and one side
is the word size of the computer?
