oooh, I2C eeprom.

I just looked about and found the Atmel datasheet for their 93c46, and
an old microchip datasheet for their version of the 06/46. 

If this is newer atmel part is representative of other modern 93c46
parts, to make the 46 work in place of the 06 you might have to make a
change - pin 6 is now a memory organisation pin, and you'll need to pull
that to VCC in order to make this chip run in x16 memory organisation.


apart from that - reading and writing I2C eeprom is pretty trivial and
works in a standard way across all devices. if worst comes to worst you
can do it with a standard microcontroller dev board and some off the
shelf code....
