Abstract
A gas panel can provide optical data readout in an essentially serial manner for copying, communication, interaction and indication. This is accomplished by using substitute sustain cycles for reading particular addresses. A complement sustain signal obtained through the address selection circuitry is superimposed on a partial sustain signal to produce the substitute sustain signal. This provides a complete sustain cycle for the selected address(es) only. Flashes of light at the addressed positions indicate storage of logical '1s' at such addresses.
