This is relatively simple : just use the built in I2C stuff on the PIC's. Basically, the way I envision the Stamp interpreter is as a giant jump table with some RAM locations keeping track of interpreter state. An opcode is pulled out of the eeprom which causes a jump to the proper assembly code with the parameter setup based on the opcode. There are, I believe a couple of microchip appnotes on talking to various EEPROMS. Search throught their knowledge base and you should be set. -Erik Reikes
