TEST BENCH FOR GOTTLIEB® SYSTEM1 DRIVER
DESCRIPTION
The are several areas on this test bench:- lamp outputs
- coil outputs
- sound outputs and audio amplifier
- knocker output
- 12V/5V power supply
Each LED is identified on the PCB, and labeled according to its function (lamps, coils, sound).
Specific power resistors on SOL6 SOL7 SOL8 and OUTHOLE coil outputs draw a stronger current (0.4A) than a LED to get closer to the real driving condition of a coil (5A or more). As a matter of fact, a bad transistor may seem to work under a low current (LED) but not under a high current (real coil).
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.
The power supply is taken from the pinball 12V, with a diode in series to prevent polarity mistakes. The +5VDC needed by the audio stage is generated via a classic 5V regulator, with a "Power +5V" indicator LED.
Compatible with all the driver boards (original Gottlieb®, Boston Pinball, Ni-Wumpf, Rottendog ...) and all-in-one PI-1/X4.
The PI-1 and PI-1/X4 boards include an additional specific test program for this bench.
INSTALLING AND CONNECTING
The test bench can either be connected on the original driver board or on the PI-1/X4 board. All the connectors are aligned, so gently push to insert:You can leave all the other connectors (A1J2 A1J3 to the displays and A1J6 A1J7 to the switches).
The 12V power supply is taken:
- either on the PI-1/X4 screw connector
- or on the big C1 capacitor on the original power supply board
