If you've used the external SRAM (as in STATIC, not serial) on a PIC or AVR-
which SRAM did you use?  I'm having problems finding a 64Kx8 part that is
pin compatible (without gates other than an address latch) and is in stock
somewhere.  I could go to a 2 32K SRAMs, but I'd rather not.

The PIC (17C) uses an ALE, /OE, /WR scheme, and the AVR uses an ALE, /RD,
/WR scheme.  The PIC appears compatible with the 61XXX family of SRAMs (64Ks
are currently being made of Unobtanium [Un]), but in my brief search, I
haven't found any that are directly compatible with the AVR's scheme.
Serial RAMs are not an option, due to speed issues.
