This post is about my recent restoration of a #Circa 1933 pinball machine by replacing the defective computer chips with an Arduino. See the story in my profile page for more details. Anyone who has technical questions or comments can ask here. For starters, here is a video of the restored machine in action.

@kenh, wow, that’s really interesting about the other machines using the same software. pinwiki is a very useful site, it could have saved me some time trying to decode the handwritten schematics!
Those connectors look like what I used actually.

Can anyone suggest a way to post my program code? A 2000-line comment wouldn’t be very convenient.

The code I wrote can be found on Github:
https://github.com/electric-piano5k/Circa1933Arduino/releases/tag/v1.0
I also uploaded there a spreadsheet with the wiring connections between the pinball board and the Arduino.
