I don't doubt something is wrong hardware wise....
I'm pretty clueless about how to track it down.
What I find interesting, and strange, is that MiNT is the environment it chokes
in, and primarily at boot-up.
MagiC, Geneva, or built in TOS don't appear to suffer....and they do things a
heck of alot faster too, in ways that one would think tax the bus even more than
MiNT's methods.  I.E. ethernet over ROM or SCSI, or moving a pile of files
around on disk.

Maybe MiNT is relying on some timers that are bad, or have bad connections?  If
I can get my hands on a spare, I'll seed the thing to CenTek for a good
tuneup...I suspect a problem maybe in the Falcon itself rather than the
CT2b...I.E. the audio inputs have never worked, and can only get one channel
input over the FDI.

The error messages I get most are:
Bus Error $02
Address Error $03
Line F emulation $?? (forget the number now)
Illegal CoProcessor instruction
