At any rate, between 1950 and 1953, the official color

standard in the USA was the CBS field-sequential system, which, compared
with the RCA system of the same time was quite good (at least for the
time)--a mechanical 3-color filter was spun in front of the CRT,
synchronized to a similar filter at the camera.
It wasn't until 1953 that RCA had improved its system well enough for
NTSC color to become the official standard.
A few CBS System receivers still exist.
Lots of vintage TV's still can be found. It is getting working color
CRT's that are the problem
from what I read on the net. Now might be the last time
to find CRT's
for vintage computer
equipment.

Has the color on modern display devices
matched the color purity of the
early TV's yet?
