    Interesting. The latest show I saw was Crystal Odyssey. If my understanding is correct, the Beatles came after that. I haven't heard of the clipper card. I don't see it referenced in the L.II system diagram hybrid card cage, nor in the L.6c system block diagram, nor in Ron's 6b alignment procedures doc.

    Sorry, the clipper card wasn't added in 82 it was added in 81. It was modified to add AO Driver in 82. I'm guessing the Clipper board and controls were added as part of the Crystal Odyssey Mods. The Clipper did what it's name implied. It gave the Laserist control over where the positive and negative ends of the X & Y signals (from the master gain control of the CYGN-A) were clipped. The two clipper circuits used one each of the AD811 and AD821 dual transistors so a it would take a bit of a redesign today. FWIW I never liked the clipper effect on the G-124 open loop scanners, and I never saw anything cool enough to make me really want to use it. I'll try to make it by UPS this weekend and send the packages sitting on my steps.

    Awesome! Looking forward to that. Yeah, I remember the opening number of Crystal Odyssey had something that was like Danube circles but if I remember right it was more like rounded rectangles. Maybe that was evidence of the clipper.
