I also think Mike could have been a little more helpful.

I recall that there are some companies out there that produce small
processor boards that are able to be bolted down onto a board that contains
the I/O portion of the project. This way, the I/O circuitry can be
designed, by the OP, to handle the automotive power supplies and transients.

The rest of the automotive environment (temperature, vibration, electrical
noise) can be managed by electronics package siting, enclosure, filtering,
and thermal management.

I wish I could remember which companies did the very small boards. Perhaps
others may know. Failing that I will have a list after I visit ESS on
Thursday.
