NG Bench test fixture - Software
Troubleshooting of electronics boards
Universal bench, for an easy diagnosis

All brands of pinballs
(Gottlieb, Bally, ... and many more).
Second part of the project
"Bench test fixture NG"
We developed the ULTIMATE VISUAL BENCH software suite to efficiently pilot our new test bench. With a multilingual graphic interface (French, English and German), its use is simple and user-friendly. It is in the form of a series of applications, each specific to a type of board. We also added a checksum calculation tool and a complex component tester.
Of course, this suite is scalable and we add maps as we need it.
Warning: the software evolves often, the photos presented below do not necessarily correspond to the latest version!
All the applications concerning board testing now include standardized functions:
- Individual BUS test
- BUS verification (short circuits, grounded pins)
- Quick visualization of the BUS on a dedicated LED module
Are currently done :
- Outil CHECKSUMS
- Component Tester
- Generic DIP Tester

This tool is completely independent of the test bench and can be used without connecting it. It allows to check and modify internal checksums of Gottlieb ROMs. It uses builders algorithms, U2/U3 system ROMs, game ROMs, audio ROMs, and for different generations of pinball machines.
This application uses the test module associated with the test bench. It allows to test the operation of complex components such as PIA, VIA, RIOT and even CRTC (video). SECURITY PICs can also be controlled in this way.
The positioning of the DIPs and the location of the power supply pins are directly displayed in the interface.
Generic DIP tester
Pilot or test individually, the pins of any DIP circuit. It is a very practical tool which allows to inject signals on a board, or on a component.
It can work in totally generic mode and thus adapt to unknown circuits, or else, in a predefined mode simplifying the control of known CPUs.
GOTTLIEB SYSTEM 80 - CPU
This application is dedicated to the testing of Gottlieb SYSTEM-80 CPU boards. It deals with both first-generation board and 80B with Piggyback.
Boards with welded components can be tested via connector TC1.
All functions are accessible easily and intuitively. Most are displayed graphically with optimal legibility. The tests of the contact matrix, lamps or displays (digital or alpha-numeric) are thus directly readable.
When checking the main components, a picture of the board is displayed for immediate identification in the event of a problem. Thanks to the 4 color dip-grips, the address decoding or BUS functions can be used to locate the faults.
GOTTLIEB SYSTEM 80 - Audio
Application for the testing of Gottlieb SYSTEM-80 advanced AUDIO boards, type MA-216 and similar, with or without SC01. It has functions similar to those of the SYSTEM-80 CPU test.
A sound generation test function is included, with different waveforms. If the SC01 is installed, the voices are also tested with variations of intonation and frequency.
GOTTLIEB SYSTEM 80 - Audio 6530
For the test of the simple AUDIO board Gottlieb SYSTEM-80, based on 6530. Thanks to its great flexibility, our test bench adapts very easily to all box formats. On these boards, the CPU is a 6503 in box 28 pins and not a 6502 in box 40 pin.
As with the advanced board, a sound generation test function is included, with different waveforms.
GOTTLIEB SYSTEM 1 - Audio 6530
Dedicated to the test of Gottlieb SYSTEM-1 AUDIO boards, based on 6530, this application is similar to that used for the SYSTEM-80. With some notable differences, however, such as the lack of a Piggyback version or the connector wiring. Likewise, the hardware and control of this board are different from the version for SYSTEM-80 (MA-55).
GOTTLIEB SYSTEM 3 - CPU
For the test of Gottlieb SYSTEM 3 CPU boards, using a CPU 6502 and VIA 6522.
VALLEY SPECTRA IV - CPU
For the testing of CPU Valley SPECTRA IV boards (cocktail tables), using a CPU 6503.
ZACCARIA - CPU Gen. 1
For the test of Zaccaria Generation I CPU boards, using a Signetics 2650 CPU.
ZACCARIA - CPU Gen. 2
For the test of Zaccaria Generation II CPU boards, using a Signetics 2650 CPU.
ZACCARIA - Audio Gen.1 1B1146
For the test of ZACCARIA Generation I AUDIO boards, using an Intel 8035 CPU.

CAVEMAN video block- EPROMS board - MA-254 (A22)
Application for testing CAVEMAN video block boards. This is dedicated to the EPROMS board and requires the CAVEMAN adapter.
CAVEMAN video block - RAM I/O board - MA-253 (A23)
