Withdrawn...
I think its future has been decided. The motor and control circuitry are on one nice board, and the motor has a convenient hollow boss into which I could fit a pulley. Yes, a turntable motor like audio origami's beckons. I even have a platter and bearing...
Looking at the motor, I suspect that 5 1/4" drives were rather like early videotape machines and relied on precision mechanical engineering to work, whereas later machines cheapened the engineering and relied on servos and error correction (failing that, reduced standards). The motor looks to be very well made, and must have quite reasonable torque to be able to rotate that large disk inside an envelope.
But thanks for the charming offer of contemporary software. I still use WP (and occasionally QuickBasic)!
