Thanks David.
So the DS2401 is just an ID chip and nothing else? Is the only point of
using a chip like this on the logic board to uniquely identify the
hardware? Or are there other chunks of the NOS that use the ID number
(like Tow's NewtonID)?
I'm probably missing something blatantly obvious, but I find it rather
interesting that this type of thing would exist in a PDA.
