Tools for pinball repair: Switch matrix & lamp matrix tester

[JarekC.DIY]

Hi,

I'm new to this forum so hello to everyone.
I am an electronics engineer and one of my hobbies are pinballs.
I live in Krakow, where there is a large Pinball Museum.
Sometimes I help with repairing and refurbishing machines.

I did a few pinball projects and I would like to present them on this forum.
These are not complicated projects but I think they are useful.

One of my projects is a "Switch matrix & lamp matrix tester".
The module also allows you to diagnose and repair the pinball ( MCU boards and Power Boards) without a connected playfield.
For example Willimas WPC system without connected switch matrix will be report errors:
"Check fuses F115 & F116, J112 & Opto 12V Supply"
or
"Check fuses F114 & F115"

The tester consists of 4 blocks:
- matrix of 8x8 switches
- DIP Switch matrix (usefill for opto & always closed switch)
- direct switches
- 8x8 LED matrix

Full documentation, schematic and wiring diagrams for Williams WPC and SYSTEM 11 attached.
Of course, the tester can also be used to repair pinball machines from other companies.
