Hi Isochronic_Frost,
I'm not remanufacturing them. The board have been made by a forum member "AmokSolderer" . I'm juste ordering the board from the manufacturer JLCPCB by using the open source files share by "AmokSolderer".
Regarding the APC board:
It is intended for people who want to start programming pinball machine and learn about electronics. Also for people who want to expand the possibilities of their pinball machine (create new rules, add feature, improve gameplay,...). That means it's going to require some work to set up your game even if you don't want to change anything, but run the original rules with PinMame witch is support by the APC.
The APC is a freely programmable controller for Williams and Data East pinball machines. It uses an Arduino Due and contains all the circuitry required to run a Williams pinball machine from System 3 to System 11c (and the compatible Data East machines):
Display interface for all corresponding display types
24 Solenoid drivers
Lamp matrix drivers for 64 lamps
Switch matrix drivers for 64 switches + 8 non matrix switches
SD card interface (to store audio files, highscores and settings)
Audio amplifier with two channels (to play music and sound effects simultaneously / can be changed to single channel stereo)
In my case since i don't have any board for my DE Laser war, it will remplace all the card excepte the power supply. So it's cheaper.
For people having a broken CPU, it's a more affordable replacement and with more features.
You can also use this board to create your own pinball machine.

According to my estimate the board will cost at JLCPCB between 20-25€ and with the Arduino and all the component that must be soldered by yourself the final cost will be less than 100€. It will depend on where your buy the transistor, Arduino, connector ....
