[Coco] Broken CC3

[George Ramsower]

Darn,

 My CNC coco broke.

 It starts up and displays the usual stuff. I can ?mem and it reports 
correctly. However, when I boot OS9, it crashes.

 I appears to crash when it loads the first boot sector.

I tried other boot disks with the same results.
I replaced the CPU, RAM board, reseated the GIME, polished the edge 
connector on the disk controller, reseated the ROM in the controller  and 
all gives the same results.

 Suggestions?
