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.

My SD1 Has an electronic speedo - but with normal analogue readout. The
odometer is driven by a synchronous motor. Solenoids tend to be grossly
inefficient. Although I doubt that much matters for this application.
