I remember learning about this back when I took a smog certification class back in community College. Learned the only computer approved to run the modern smog diagnostic stuff is from 1986 and it’s made by like one company to this day.
Add onto that all the dinosaur lathes and welding machines I’ve seen over my career and I wouldn’t be surprised seeing a commodore running the dmv database for the entire state at this point.
Well that’s not true. It’s just a real bitch. As a welder, helium leak check is about the toughest damn QC to pass. Most welding QC has some reasonable margin for error during inspection, but the damn helium doesn’t care. You can have a beautiful weld with a tiny imperfection at the start or end and it’ll piss helium just as badly as an entirely scuffed bead.
