Test Fixture Gottlieb System 1 driver
Test Fixture bench equipment for Gottlieb® System1 driver boards.
Designed by Pascal Janin.
This board assists in troubleshooting the following circuits of a Gottlieb System 1 driver board:
43 indicator LEDs show all lamp and coil outputs
Each LED is identified on the PCB, and labeled according to its function (lamps, coils, sound).
As an option, SOL6 SOL7 SOL8 and OUTHOLE coil outputs can draw a stronger current (0.4A) than a LED to get closer to the real driving condition of a coil (5A or more).
The 3 sound outputs (10 points, 100 points, 1000 points) activate 3 LEDs and 3 oscillators to recreate the basic sound board used on pinballs from CLEOPATRA to PINBALL POOL.
The knocker output activates a buzzer.
Power is used from the pinball 12V, with a diode in series to prevent polarity mistakes.
INSTALLATION AND CONNECTIONS:
The test bench can be connected either on the original driver board or on the PI-1/X4 board. All the connectors are aligned, so gently push to insert:
