and now hoping. OOI, how does the odo display (0 to 9 old style rotating
disks) work?



The one I took apart had a solenoid with a pawl on the end, pulling a
ratchet on the end of the odo shaft.

That makes sense but there must be a highish gearing on the ratchet, maybe
500 teeth per mile? The 1/10 mile disk looks really smooth to the eye.
