Pentacup
About This Machine
The Pentacup, manufactured by Micropin Corporation in 1979, is a distinctive tabletop/counter solid-state electronic pinball machine. Its reliance on a 6800 microprocessor allows for ball tracking and control via solid-state sensors rather than traditional mechanical switches.
Gameplay features are simulated using wireforms, creating a compact pinball experience with flippers, pop bumpers, slingshots, kick-out holes, and stand-up targets. The machine's solid-state sensors detect the ball's motion, while tiny solenoids or stepper motors activate the various playfield elements. The absence of coin mechanisms is a notable aspect, as credits were added manually via an attendant-operated push button on the rear panel.
The Pentacup's design is characterized by its brushed stainless steel cabinet, giving it a sleek, modern countertop aesthetic. With only around 90 units produced - reportedly cut short after the game was found to be an illegal gambling device under California law - its rarity adds to its appeal for collectors and historians interested in the development of early solid-state pinball technology.

Technical Details
- Notable Features:
- The following playfield features are simulated using wireforms: Flippers (2), Pop bumpers (4), Slingshots (2), Kick-out holes (6), Standup targets (5). Based on 6800 microprocessor. Playfield lights are red LEDs and score displays are red 7-segment LED displays. Solid-state sensors detect all ball motion and tiny solenoids or stepper motors activate the flippers, slingshots and pop bumpers. There are no coin mechanisms; credits were to be added by an "attendant" via a push button on the rear panel. Cabinet is brushed stainless steel.
