There was actually a storage tube prior to 1961. The first F-4 Phantom II
was flown in 1958 and the radar
scope was a DVST (Delayed Vision Storage Tube). The image would pretty much
stay on the screen
indefinitely unless an erase pulse was applied. I don't know if this is the
same technology that is in a
storage oscilloscope but maybe some of you retired Tek guys can say. Does
the storage oscilloscope
need an erase pulse?

Just as an aside, the brightness adjustment on that radar scope was
non-electronic. The screen had
two Polaroid lenses in front of it and you adjusted the brightness by
turning one of the lenses. If you've
never seen that, find an old pair of Polaroid sun glasses and take the
lenses out. When the polarization
of the two is 90 degrees apart, you can't see through them.

Stan,

I that book that you look down at, 'Winning with People', there was a
mention of a guy by name Bob Anderson, who was hired from Hughes in 1959
(page 214, right hand column). He started at CRT department, working on
general CRTs, but by late 1961 there was a storage tube, and Bob Anderson
was associated with it. The storage CRT enabled 564 to be brought to
market
in 1963.

Maybe that is a link between Hughes and Tektronix storage CRT, that we
speculated about a while back.
