Hey, I have one too.

A Calcomp 1042GT.

It can't run for 10 minutes without loosing it's brains.

Haven't tracked that one down yet.

Not that that has any real bearing aside from the suggestion to
add some decent diagnostics and failure logging to any system

It would be a good idea to have it sooner or later, when a
sensor goes off or gets dirty.
