Theory of Operation
The Robotics Controller PCA
generate a vacuum filament display using a 7.5-volt supply tied to a
5-volt reference, which results in an excitation voltage of from two to
three volts. The grids of the display are at approximately 20 volts.
Buffers for incoming control panel switch signals and signals from the
mailslot sensor are also handled by the control panel drivers.
