đ Thank you Adelaide! We are finally back from the Australian Pinball Expo, where we were looking after 200+ games over the course of the weekend! While it was full on, we got to do some pretty special stuff.
đī¸ Worked on an Atari Hercules. Largest pinball machine ever made. Only a handful of people on the planet have ever worked on one.
đē Set up and fixed some rare 1960s electromechanical games. These games are almost as old as my parents and are in way better condition! Fantastic pieces of pinball history.
đšī¸ Played some cool games I've not seen much of before. Gold Wings: awesome soundtrack and a fun layout. Al's Garage Band: not many of these Alvin G games around. Whoa Nellie: love the retro-style playfield. Funny, too!
đ¨âđ§ But of course, we spent most of the weekend repairing games as they broke down. Do you know what's involved in looking after this many games over the course of a weekend? Now you do, because below is my repair log (not counting the 50 or so stuck balls we had to attend to)!
Swords of Fury. Lost settings. Text in German and not in free play. Verified battery voltages and changed settings as required.
Strikes and Spares. Mid pop bumper not activating. Switch adjusted.

Harry Potter. I/O board issue. Reconnected USB at PC and driver board.

Elton John. Lamp board comm issue. Replugged I/O board.
Fire. Slingshots not working. Coil fuse blown. Upper ones locked on. Disconnected them. Attempt transistor repair but did not stop them locking on. Likely CPU issue related to battery corrosion (extensive).
Star Trek TNG. Left launcher coil not working. Broken wire. New wire run and repinned connector.
Devil Riders. No sound. Sounds board not plugged in and volume pot set too low.
Duotron. Ball stuck in centre hole and would not eject. Game not sensing ball due to dirty switch contact.
