Custom Program for a factory computer

This is a little different than what you had in mind, but I believe
I'm close to being able to merge an efi332 board with the I/O section
of a '7730. The advantage is that the CPU will have the speed and
resource to run an RTOS based code (which the original 6811 variant
could not) and testing will not require any wiring harness changes to
the vehicle [that is in my case, '88 TPI now running '7730 with '92
cal axxc]. Only needing to move the ecm connector to change computers
is the goal. This seems to me a reasonable next step in the efi332
development.
