I just
want to mention that there were polar-coordinate tubes. They may be
Interesting,. I'd not heard of those before. I will have to try to find
some data sheets, etc.
I don't recall them being mentioned in the ook 'CRT Displays' (part of
the Radiation Lab series), but I may well have missed them.
