According to an e-mail I received from Michael Anderson regarding the
Spybotic brick there is
"4k EEPROM for persistent program storage (256 bytes available for general use)"
To me this sounded like only 256 bytes were available for downloaded
programs (i.e., general use rather than firmware use). I hope I'm wrong.
