Pinball Repair - Arduino Upgrade

[@DDE100]

Amazing, thank you for sharing this.

My pleasure! The more effort I have to put into solving pinball issues, the more I want to get this information out there for others.

Good job. Way better rules. I need to get one of these machines.

Thanks, much appreciated!

Not sure if all Solid State 70s and 80's pinball games watchdog circuits during power up boot sequence would shut the pinball game off and reset the pinball game if any coil is locked on or shorted which I'm not sure if the watchdog circuit did this or not?

Interesting question. I haven't heard of this, or read it in any manual, so i would have to say no. It's a good idea though. Maybe I'll look into how the arduino might achieve that.

I just checked an Alltek manual for their solenoid board, and it goes through a check for stuck coils as you suggest. So, the 70s/80s pinballs can be upgraded to do this.

@@davesthinktank Yes but only the Alltek replacement boards do this check for stuck coils. Its something in the boot sequence program loaded on the ROM chips but the 70s and 80s ROM chips don't have this check for stuck coils doing the boot up so the watch dog circuit on the Alltek boards are different also to check for the stuck coils it seems.
