As a little side interest the guys at Mistral are using a computer that
does exactly that. That is, it automatically switches between computers at
failure. Expensive but nice for certification. There is a test circuit that
checks BOTH ecu's before startup.

Bill,
That's a great feature - I'm sure Tracy will get there eventually.
I think Mistral's is 3 or 4 thousand dollars?
