How a Tracing Board Works

The electronic board is a grid of wires going up and down and across with a hard formica surface. The pen stylus or cursor generates a magnetic field that is "sensed" by the board. Push a button on the pen or cursor or push down on the tip of the pen and a stream of accurate XY points are sent to the computer. The Logic Trace software then displays these points as a drawing or numbers.
