Can someone identify this S100 SRAM card? I can tell that it's a 16K SRAM board

Whoops!  How about if I show you the picture?

It looks very close to a California Computer Systems board, possibly a 
different rev.

It's closer to the JTM 16K Static RAM, which must somehow have been related to 
CCS.

If you take a look at the manual for the CCS board on the s100computers.com site, you'll find a Revision B diagram that appears to be an exact match (page 39):
