Forget 3rd party - buy the CMOS RAMs from a supply house.  It's
a standard low power CMOS 32K RAM (nothing special about it at all-
I checked v.s. other similary low power 32K static rams).  I got 
mine for less than $8.

No. The 32K fits the lower pins - there are 2 or 4 pins (I can't
quite remember) at the top which are not used.  I'm not sure if they
are WIRED on the board, though.  It appears not.  Like they put
a 'standard arbitrary EPROM socket' on the board, even though
they wired it for EPROM-pin-compatable RAMS of 32K or less only.
