yep.  It's a servo feedback input.  I'll feed it into the A/D on an '876.

I guess hall sensors could work.  I should be able to use two bipolar hall
sensors and a small magnet, yes?
Kind of like an analog version of the optical encoder. hmmmm...

Not sure if I can get one that gives 10-bits resolution in a 1/4" package.

The hall sensor idea has intrigued me.  Anyone else done this?
