of a sensor) a bit of a problem.

Hi
The plan was to use a 3.5 disk on a H89 or N*, not read them
on a PC.
Some of the older drives had a flywheel. A drill, in indexing jig, a
light and photocell, any you could modify a 3.5" drive to provide 10 or 16
pulses from physically fixed positions, without being dependent on
repeatability of rotational speed.
