That's a lovely self-portrait, Jim.

Impressive home lab, Bernice, and nice photographs of the setup. The scopes I used were always my employer's property. I never used a 7104 but I used a 2467B with the microchannel plate. I used to call it the "Magic Screen" (with a hat tip to PeeWee Herman) because you could see things with it that were otherwise completely invisible. It was a beautiful instrument. Eventually in my last job I used a Tek gigabit/second digital sampling scope. I have to say it was great for some things, but I don't know if I'd trust one to see the quick one-off glitches that can cause those mysterious intermittent problems.
I could be wrong about that, and I probably am. But I'm retired now, so it doesn't matter.
