Abstract: A control system for a data display system such as a scoreboard, message board or the like wherein display indicators having location addresses, on the board are addressed and actuated through a logic system which first receives and stores address data pertaining to a particular indicator, receives display character data, and responsive to the receipt of the character display data automatically reads out the address data to the board for enabling the desired indicator followed by the display character data to actuate it to display the desired character. Indicator circuits are provided for the control of each indicator comprising semiconductor switches which are reset by the addressing of the indicator and actuated to display the desired character responsive to the receipt of the display character data. A memory storage is also provided to cause the display of repeatedly used messages and animated characters.
