The following functional description is from the Model S Owner's Manual written by the Skee-Ball Corporation:
"Functional Description
After the proper number of coins is inserted the microprocessor turns the ball release [servo]. Until the proper number of balls is released, the following conditions should exist:
A. Score is 000
B. Ball Played is 0
C. Winner, Free Game, and Game Over lights are off
D. Tune will play after coin is inserted
The alley is now ready to be played. If a ball is rolled and goes into the fifty pocket, the score will increase by 10 every time it passes one of the score switches. Therefore, after the ball reaches the bottom of the score track, the score should have increased by 50. Also shortly after passing the last switch in the track, a tune should be played by the microprocessor. Each pocket has its own individual tone. If however during the scoring time a winning score is achieved the winner song is played instead of the pocket sound. This is also true if a free game or high score is achieved. Each achievement has its own sound.
After the ball has been rolled and score has increased the balls played should increase by one as it passes the ball count switch. If the ball does not go into any of the pockets (a gutter ball), a gutter ball tone is played and the balls played are increased by one. When the last ball is played, the score will flash for (approximately) 20 seconds. During this time the player can start his [or her] free game , if achieved, by depressing the [start button.] After the 20 second delay, the machine will go into attract mode. If a free game was won then it will now be dispensed automatically."
The machine shall also have a free play mode, that by-passes the coin mechanism.
In addition it shall have an android companion application, and a liquid crystal display interface.
