I’ve always had been fascinated by technology and electronics, and I can remember the first time I used a scope. It was in my high school auto-tech class, and we were being intro-duced to ignition waveforms using a Sun Engine Analyzer. I pulled my 1968 Barracuda up to this huge machine with all kinds of leads coming off of this big arm that hung over the engine bay, and everyone in the class was overwhelmed by what was going on. It was amaz-ing to me that my teacher could tell that my points (anyone remember points?) weren’t gapped properly and that I had a bad plug or wire on #3 cylinder simply by looking at the electrical signal on the scope.
