Programmer's screen
Press and hold the 1, 2, and 4 keys on the player 1 control panel before the title screen music stops playing. If you are still holding down the buttons when the music ends, the programmer's screen will appear. It reads, "PROGRAMMED BY WILLIAM HAWKINS GT 1982." The screen will go away after about 2 seconds or until you release one of the buttons.
NOTE: This will only work when you first turn the game on.
