I've had at least two 6809s go bad, though I don't recall the exact symptoms.

But you are likely right that the GIME would be a more probable
suspect.  That raises an interesting question:  Would one pay ANY
money for a CoCo 3 with a bad GIME?  Or are GIMEs now so unobtainable
that replacing one would cost more than the machine is worth?
