1. So I assume that I can reset the latch by stepping the head? That's
good to know. It would require a microcontroller sitting next to the
floppy control chip to step the head periodically. It could be done with
a 8-pin PIC I suppose.

2. How does 1581 work then, which uses the same mech but does not "click"?
