Jeeps....
When a chip is manufactured, it has a model number and a unique serial
number hard wired into the electronics, and also printed or stamped on
the ceramic top surface.
The model identity and serial number can be checked by simply reading
it off the surface, or as a double check against fraud, obtained by
reading it electronically from within the chip. The ID is not flashed
into the electronics, as this could be changed..... it is hardwired
during the assembly process.
The CPU within your PC or MAC is one example.

EPROM identity codes? Not a computer guy, but have a question. Might
these identity codes sort of be a key to enter the program; thus
allowing one to alter programing. Maybe I'm thinking of source code?
Or is it not nesessary for a computer person who knows how to change
things?
