The renowned pinball and arcade collector, Jon Exidy Jamshid, recently shared an amazing finding over on the in "Pinball Enthusiasts" Facebook Group. A friend of his recently purchased a prototype of the 1982 Stern Electronics Orbiter 1 pinball machine, which in itself is super rare. Inside of the game he found polaroids of a never before seen prototype pinball machine called "Clone."
This thing is wild. A Google search for this game literally turns up zero information on it. It looks like the playfield was similar to the unique Orbiter 1 playfield that uses hills and valleys to create an unusual gravitational pull-like effect on the pinball.
