Abstract
A modular control system is provided for a gas panel of the type having an array of row wires and column wires that form light emitting cells at their crossover points. A row counter and a column counter provide selection signals for entering characters sequentially on the panel. The counters provide borrow and carry signals to components that control the display. Thus, the control operates without regard to the actual size of the display and provides a modular construction for displays of various sizes.
