I saw IMD's ad in a very recent issue of MicroTimes/Computer Currents (monthly
and bi-weekly), I guess the ads are out of date.  When calling just ask
for 32 KB x 8 SRAM (or static cache RAM).  Since IMD deals mainly with
memory, I'm pretty surprised that they carry no more SRAM.  Thanks for the
info though.

You can also tell them the chip number (ones from previous posts), and they
should be able to convert it to other vendor's chip that are the same size.

Yes, they are available for Digi-Key.  No one has tried them yet (no one
reported atleast).  A friend on IRC has the adapters, but he don't have the
SRAMs yet.
