NI-WUMPF – Gottlieb System 1 Driver Board with Fault Detection

The original Gottlieb System 1 driver board is known for CPU corrosion, hard-to-source components, and damaging transistor failures. The NI-WUMPF board is a modern replacement designed to solve those problems—and prevent future ones.

Equipped with fault detection circuitry, diagnostic LEDs, and FET transistors, this board makes identifying and servicing failures far easier and more affordable.

Key Features:

• LED fault indicators for each solenoid
• FET transistors and higher-rated components
• Diagnostic LEDs stay lit when components are unsupported
• Diode-isolated grounds prevent lamp-related faults
• Modern open-collector interface to buffer sound board signals
• Fully discrete components for low-cost, easy service
• Field-replaceable parts (no proprietary arrays)

Designed for reliability, clarity, and long-term support.
