Re: CRT book by Keller


Maybe a dumb question, but did they pull a vacuum on the coke bottle?

The Coketron actually has no components inside the Coke bottle. It takes what
I believe is a 1EP1, sans screen, and mates it to a Coke bottle. It actually
has deflection plates (at least, that’s what I recall from visiting
Vintagetek, where they have one on display), so it has all the guts of an
electrostatically deflected scope crt.
I never saw one light up, though.

That's what I figured. The neck of a Coke bottle is pretty narrow to get
