Need static RAMS for ZipGSX

[smcgroga@pippin.Advent.COM (Stephen McGrogan)]

Is there a commercially available source for the 32K static wide-base
RAMS used in the ZipGSX?  My zip currently has 32K and I'd like to enhance
it to 64K.  The current RAMS appear to be 70ns (not particularly fast),
since they have a -07 suffix.
I can't find matching parts in Mouser, Digikey, ....

Alternatively, does anyone have parts that they are willing to sell?
