Emax

The Emax 2 has an EEPROM chip that presumably stores configuration 
parameters (headroom, SCSI boot ID etc) and hardware authorisation codes. I 
notice it is soldered into the motherboard but it probably wouldn't be too 
hard to desolder it and read out the data. I expect the Emax had a similar 
EEPROM for storing the SE update authorisation etc. 

The Emax 2 memory expansion PALs appear to be preprogrammed and come 
supplied with the memory chips/memory expansion board. I doubt there is any 
circuitry to allow the PALs to be reprogrammed or modified in circuit.
