Extrenal EEPROM

I know it is possible to add more EEPROM via serial connection to the basic stamp for long term storage data and stuff. But is it possible to store program code onto it? or are there any other uses for it besides what I already mentioned?

    EEPROMs can not be used for program storage.· They only stores data·by bytes, but you can store up to 256 bytes at one time.

    External EEPROM can be easily interfaced to the BS2sx and the BS2p via I2C. The BS2p(which I have not used yet) can even for example take a program on an external memory module or IC and copy it to a specific bank... This allows alot of flexibility as your banks can be modified depending on the needs of the project in real time.

    I have recently interfaced a 24LC515 512Kbit EEPROM to a BS2SX and it works great(and has a 64byte page write·devil.gif
    Check the StampWorks Library on the Parallax website (StampWorks Experiment #32: I2C Communications) for a demo using a smaller EEPROM, the 24LC32.
