But I made notes about the head connections for who
wants to dig.
Serial is 1509S07*** but I have another one with the serial 1506S05*** witch
has the head filled with epoxy.

IIRC, the Red and Yellow wires are one head winding (presumably a track
nearer the display end of the calculator), Blue and Orange are the other
winding, and black is a grounded screen.
I think the data format is that a pulse on one track is a '0' bit and a
pulse on the other track is a '1' bit.
