Located in slot 3 of the Basic Operator Station chassis, the Display Generator card receives station data and converts it so it will form characters on a CRT or LCD display. The card allows up to 80 characters on 24 lines. Data from memory is buffered on this board, stored as codes to define all the characters for each line, their color, and blinking status. Board has no LEDs. Jumper is located near the front of board.
