A few people have had trouble locating the motor for the propeller clock, so
I've figured out a way to use the motor out of old 5 1/4 inch full-height
floppy drives made by Tandon, like the original IBM PC had.

Give me a few days to do some refinement of the modification process, and
then look for an update. I'll send a message when I've got it done.
