That’s the original HyGain RotoBrake controller. A little tough to interface
directly to anything else because it uses a 400 cycle selsyn with a 5:1 gear
train. Very nice display though. Of course now it’s way easier to get a
display like that on a computer screen that is centered on your QTH. This
display is centered (if I remember right) on central US).
