I have isolated the problem to the spindle motor control board, since: A. an exact replacement mech works just fine in the machine. B. Spindle bearings are free with no excessive play. You CAN get the drive motor to spin if you give it a bit of a push-start by hand, but 9 out of 10 times the thing won't start on its own. *Geoff!* - This message was sent through the cbm-hackers mailing list.
