Quoted from roffels:Don't a lot of Stern's kill the ball if you open up the coin door?
You're correct, but there's a way to disable that. Here's a quote from my TSPP manual.
Adjustments - Standard Adjustments - 42
"Coindoor ball saver: Set to YES or NO. Default is NO When set to NO, this feature is not available. When set to YES, this feature allows the Coin Door to be opened during game play; the ball will drain but the game will be placed "on hold". When the Coin Door is closed, the pinball will return to the Shooter Lane, and the game will resume."
