Brother knitting machine motor KE 100 with Electronic Counter

Brother Knitting Machine Motor Drive unit KE 100 with very rare electronic counter, sensor, foot pedal. Shown working on a brother kh 260 chunky/bulky knitting machine. I have not done knitting on the machine neither the needles are in working position. All I am trying to show here is how a working motor works and specifically how the counter works on ke 100 drive.
