Sinmce the rotator has an analog position readout, it strikes me that it is
probably a simple voltmeter. If you can figure out what full scale is, you
might be able to get a DMM module that could be calibrated to give you
something more precise.
As for the computer control, there's a company that makes a fairly
versatile controller interface that will drop into most rotator
controllers, but the Yaesu OEM interfaces were ridiculously expensive.
