Quoted from Mtkst19:Look into gottlieb spring break. It is the oprah of multiball.
3 ball game.
Dipswitch 31 ON starts the game with
3 balls per game: 2 balls on ball 1, 3 balls on ball 2 and 4 balls on ball
3.
On a 5 ball game: 2 balls on ball 1, 2 balls on ball 2, 3 balls on ball 3, 3
balls on ball 4, 4 balls on ball 5.
Dipswitch 31 OFF releases all 4 balls on the first ball in play only.
1 ball is released on every subsequent balls.
In the game you can shoot the 1, 2 and 3 targets to light "release a ball".
Which alternates on 3 rollovers, and one being "release all balls".
In the later rom version it was changed. Setting dipswitch 31 to off gives you single ball launches on each of the three balls. To start multi ball you have to hit the 1-2-3 drop targets and roll over either of the lit release ball switches that change with the pop bumpers to add a ball. You can repeat the 1-2-3 and rollover to add more balls, or roll over the release all balls switch on the right inlane while lit for a 4 ball multi ball.
