Hi Lars, I hadn't booted this up for a couple of weeks so I thought that I would check it out today and when I first turned it on the solenoids didn't kick in so I thought this would be a great time to make a video to show how to fix it! I rushed to get a camera and then on the second boot up it worked fine but I went though the procedure anyway! It was built in 1982 and the first Pinball machine to have integrated circuits!
