Clone

Clone is a solid-state prototype pinball machine developed by Stern Electronics, Inc. in December 1982. It was built on Stern's M-200 MPU and features two flippers with a digital score display.

Clone never went into production; only a single unit is known to have been made before the project was abandoned. As a one-off prototype it is exceptionally rare and largely undocumented, and it is not yet listed on IPDB. The information here comes from the Pinside machine database.
