Question
Any chance you could tell me how to get my screen to rotate from 1 to 2 player. The machine has been restored and the monitor is fairly new. It worked fine until the battery died and I believe it went back to the factory upright setting.

Thanks

Answer
Here is how to set the cocktail back to the correct settings, straight from the original owners manual:

BOOKKEEPING AND EVALUATION TOTALS (Functions 1-7)
=================================================
1. In game over mode, set switch to AUTO-UP and depress ADVANCE. The CRT
  indicates Function 1 and total left chute coins.
2. Record audit totals and depress ADVANCE for functions 1-7. To review a
  total that has been advanced past, set switch to MANUAL-DOWN and depress
  ADVANCE. Functions are displayed one at a time as follows:-

        1          0      (Total) COINS LEFT
        2          0      (Total) COINS CENTER

        6          0      TOTAL (Play) TIME (Minutes)
        7          0      TOTAL SHIPS (Played)
        
3. Operate ADVANCE to display Function 28, SPECIAL FUNCTION. From Function

  over.
4. With switch set to AUTO-UP, perform a. or b. as desired.
     a. To return to game over depress ADVANCE.
     b. To zero audit totals and return to game over, operate HIGH SCORE
        RESET to indicate "35" on CRT Function 28 and then depress ADVANCE.

GAME ADJUSTMENTS (Functions 8-27)

1. In game over mode set switch to AUTO_UP and then depress ADVANCE. The CRT
  indicates Function 1 and total left chute coins.

  set to AUTO-UP. To lower Function number operate ADVANCE with it set to
  MANUAL-DOWN.
