Changing the EEPROM
To change the EEPROM, open the processor as described on 74.
Be sure before opening that the unit is
disconnected from power.
To avoid damaging the EEPROM, please
observe the requirements for handling
electrostatically sensitive components.
The EEPROM is replaced by unplugging
and plugging back into the socket.
