1 Introduction
Orbitor 1 is that Stern Electronics game that had the wacky playfield that curved all over the place with a piece of plastic on top that was shaped like craters.
- Date Of Manufacture: February, 1982
- Production: 889 units (confirmed)
- Theme: Outer Space
- Notable Features: Wide Body, Flippers (2), Spinning bumpers (2), Slingshots (2), Standup targets (8), 7-bank drop targets (1), 3-bank drop targets (2), Spinning target (1), Kick-out hole (1), 2-ball multiball, speech. Clear, contoured plastic playfield has a "moon surface"-like substrate. Playfield slopes down and in towards the spinning bumpers which fling the ball away. The playfield slopes behind the flippers, allowing balls to be flipped backwards and then rescued for a forward-flipping shot. The kick-out hole always traps the ball landing in it, until released for multiball.
