I have just got my first 'modern' machine, Jurassic ParK. (My last machine was a Bally 'Silverball Mania').
It works OK execept for when it starts the game, before it launches the first ball, the right side vertical up kicker fires continually for about 5-10 seconds before you can fire the ball. It does this for each ball.
Is this part of the game, or is it a fault?
