Grant,
There is a Dallas semiconductor chip (DS2401) that is a silicon ID.
It has a unique 64-bit number programmed at time of manufacture.
This can be read by software (i.e. Newton ID).
If you send your newt to Apple and they exchange the MLB of course
the ID will be different because a physically different chip is there.
Unless I have overlooked something, the chip is only in the MP2x00
series. It may be in the emate, I haven't looked yet.
Regards,
David Humphreys
