Believe they are long gone. But I have the VBI-360 out here, and
the manual. There is no info in it about the rotor you describe.
However, there is info therein for use with "non-commercial"
and other rotors not listed in their then manual. Maybe that
could be of some help? I could copy off and mail a few of the
pages to you if desired. This Section 3 of the manual gives
circuit info for both two and three wire potentiometers in the
rotor; ought to be no particular trouble to set it up with your
