Static RAM chip source (& S-100 related questions...)

[Chuck Guzis]

Another option is the InMOS IMS1203 CMOS SRAM.  Same pinout (it's a 
JEDEC standard, so other examples probably abound), fast (45 nsec) 
and low power (80/15 mA active/standby current).

Shame that you need the 4K parts.  I have a whole potload of the 16K 
20-pin parts.

FWIW,
