Kenwood KC-6060 Auido-Lab Scope
Check out the Kenwood KC 6060 scope. Jeffrey Jackson pointed one out to me in his barn but I only just started researching it. This is a cool gadget. I'm sure in the 70's guys would get baked or whatever and watched the patterns but it also has some helpful features.
This video is so cool. If I ever see one out in the wild I will pic it up.
