Uh, how much more memory?  For under $1/Kbyte, you can add serial EEPROM
chips quite easily.  (snip)

 -----------------------------
Problem with EEPROM is 10*6 write cycles typically (for Microchip parts).
It depends on how often one needs to write. Every 10 minutes would be no
problem. But every second could be.

What other storage options are open to PIC users for extra memory?
Philips has a 256 byte static ram chip with I2C. But are there other
serial static ram chips? One poster suggested using static ram chips such
as are used in PC cache memory systems, but
I suspect these would be messy to interface to.
