Some recent threads reminded me of how much I liked glass diodes when I was a kid. They seemed so cool. Pretty, and finely made. They seemed marvelous, and how you could manufacture them, so tiny and perfect, provoked a lot of thought.

I also really liked vacuum tubes because you could see the parts in there, and picture how they worked.

My ultimate electronic memory is from the fifties; a large three phase mercury vapor rectifier, flickering and glowing - like a sci-fi Martian in a bottle!
