Uncle Klunk Controller

The Uncle Klunk Controller is a hardware system used to control Uncle Klunk after his installation in some Showbiz Pizza Place locations.

History
The Uncle Klunk animatronic character and various stage props required several additional control bits on top of what was available to the standard Rolfe and Earl character, which was replaced by Klunk on stage right. This required the development of an additional system to control Klunk's stage, which would work in tandem with the standard Gray Box in the Rock-afire Explosion Control System.

Technical details
Having internal 5V and 24V power supplies and not requiring any interface to the rest of the show other than receiving a feed of the top drawer data from the main tape deck, the Uncle Klunk Controller was essentially a self-contained system. It is believed that data bytes which normally went unused in the typical Rock-afire Pianocorder-based data format were used to control Klunk. According to the Klunk installation tape, the controller supported 30 outputs, divided into two connectors to which the ribbon cables from the valves were connected.
