Greetings:
With the anniversary of the Polaroid
camera a couple days ago, it brought to mind the
good(?) old days of doing o-scope and spectrum analyzer
screen captures using Polaroid cameras and the hoods.
Of course at the same time was the use of x-y pen
plotters. Now that most TE comes with a USB, GPIB,
or printer port, those days are mostly gone. My
guess is that except for in people’s basements and
garages, there are not many locations remaining
where the aforementioned plotters and cameras are
still used.
You can still find some of the hoods on
eBay,

as well as x-y pen plotters/recorders

How about you: Are you old enough to have
used the Polaroid camera?
