[Coco] Broken CC3

[George Ramsower]

 I forgot to mention that the computer started crashing while operating just 
before the total failure.
 The disk drive wasn't used at those times.

 I'm beginning to think I may have a problem with the switching power 
supply. I'll hang a scope on the five and twelve volt lines later to see if 
there's a problem there.
