I think it would be a great experiment... My wonder is if the GM chip may
have a small segment of code in the Masked ROM of their HC11 that maybe
fires things off... Reason I wonder is the reset vector seems to only pull
about 2 or 3 other subroutines in and loop when it's invoked... Even all
the interrupts don't go out and make the HC11 access any of the other code.
