Keep individual modules and their screws separate to make it easier to re
assemble it correctly
The eeprom is a NXT P24S08 which is equivalent to a 24RF08, so any
reference in the following text any reference to a 24RF08 applies to this eeprom
NOTE: VCC is NOT connected, the ThinkPad
supplies power to the eeprom later on we will switch on the TP to analyse
the eeprom.
