I've been trying to troubleshoot an issue with a IIc internal drive, but hitting a wall in my skills - I hope someone here can provide some insight.
On boot, the drive will spin up, the head will move back to track 0, but it will not read. This issue is not related to the analog board or the speed control board, as I've been able to swap in known-good boards and the symptom is the same.
So I'm supposing that there is an issue with one of the connectors or cables to the stepper motor, or perhaps something to do with the r/w head.
Has anyone had any experience with this, or have any suggestions of what to be looking for next?
