Yes, what I found seems to have been a 44-SOIC SRAM.
512*16 @ about $9.30 :

PLCC would have been better, since there are sheap hole-mounted PLCC sockets,
and the CPLD is a PLCC package anyway...

Anyway, there are many different SRAM's there.
As an example, you cold get two 128*8 SRAMs for a total
of less then $6...

And Cypress has 32k*8 SRAM's in DIP package...

Or maybe 2 512k*8 in SOIC (using a pair of cheap SOIC sockets) @ about $8 ?

Or a pair of 128k*8 in SOJ @ about $3 each ?

If one need 16-bit wide RAM, the selection gets a bit more limited...
And with 8-bit wide SRAM's maybe the second "bank" could be made optional ?

Anyway, "someone" has to think over this, I'd guess. :-)
