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.

I saw your "Pinside Story" and was intrigued. Nice to see a video of this in action!

Besides Take Five and Circa 1933

Roy Clark The Entertainer also has same Playfield layout and gameplay

Really, really nice work. I want to try a glo ball in my Roy, I hear it spices gameplay up a bit!

OK, this is awesome!

Quoted from pinwiki.com, https://www.pinwiki.com/wiki/index.php?title=ALI/Fascination_Repair#Introduction

4.3.2 Generation 2, All generation 2 solid-state ALI / Fascination games use the exact same MPU board and software; game "rules" are changed simply by rearranging the placement of switches, targets, lamps, pop bumpers, and other elements on the playfield.

So your modification could potentially bring back all these games and possibly others where the custom IC's are NLA:

Take Five
Flame of Athens
Hearts Spades
Disco '79
Star Shooter
Circa 1933 (Fascination Int.)
Eros II (Fascination Int.)
Eros One (Fascination Int.)
Roy Clark The Entertainer (Fascination Int.)

You could clean up the installation a bit by making or buying cables that use something like the DuPont type male-male connectors and they are relatively cheap.

@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.

That is so cool! Gee I wish I was that smart.

Very entertaining game! Owned a few take fives and roy clark games. Those 4 drop targets are super compelling IMO!

Outstanding work! If you need a location to upload the file contact me and I'll host it for everyone.

+1 on Github. Really easy to use and free. Its a great place to find code for about anything you can imagine.

If you want to see an example you can check out my Black Hole disc blinker/motor controller board there:


You could post your entire project there, with photos, videos, assembly instructions, code and so on.

Its awesome that theres now hope for some of these games that have been bricks for decades due to unreliable and unobtanium components. Nice work!

The code I wrote can be found on Github:
I also uploaded there a spreadsheet with the wiring connections between the pinball board and the Arduino.

Awesome project! Thank you for sharing!!

OP forgot to say excellent work and absolutely amazing that you are willing to share with the community!!!

Have a great day and play more pinball!

This is so freakin cool!!!

Now if only the arduino could do something about our clunky Allied flippers.

I feel like something should be added to the pinwiki in the Allied Leisure section. This is potentially the only way to revive these games if the 6530's are dead.
