Unbelieveably, there were several but two or three did use a wheel.=20
A Canadian product that placed a scrollng "moire" screen between=20
the viewer and the CRT and included the color decoding=20
electronics that got hardwired into the TV was wrtten up in=20
Popular Electronics or Popular Mechanics magazine in 1956 or '57.=20
There were two color wheel systems that worked with NTSC, one made=20
by Color Converter, Inc. of Columbia City,Indiana, which was called the=20
Col-R-Tel model 100-1.=20
It came ready to install and included a nicely packaged color wheel=20
and an electronic chassis that had to be hardwired into the B&W TV.=20
Heres an article with pictures about it:

The other was a kit available from Colordaptor of California. This one =

written up in a two or three part construction article in Radio =

magazine and included major parts but the builder had to make his own =
wheel=20
and provide most of the electronic parts. It was very similar in =
appearance=20
to the Col-R-Tel system.
There was an article by Jay Stanley in Radio and TV News about building =

color TV Projector with three Philips Protelgram projection units.=20
A later add-on to this article detailed building the color projection =
system=20
with one Protelgram unit and a color wheel.=20
I also remember another construction article in either Radio Electroncis =
or=20
Radio and TV News that gave a complete description of converting a B&W =

to a color set by installing a 21 inch round delta gun tube. That one =

really complex because of the convergence circuitry as well as the color =
circuitry.

Was there such a thing as a color STB? Seems to me that rather =

(today) STBs take in DTV and output NTSC. Nothing like that in the =

world (save the color wheel.)

History tends to repeat itself.
For the past 5 or so years I have read comment after comment=3D20
on this list about how very long it seems to be taking to make=3D20
the transition to DTV.
A good indication of how it's going can be had by looking at how=3D20
many "DTV" sets are being sold today and also looking back to see=3D20
what percentage of sets sold were color ten years after the FCC=3D20
approval of color.
What other means is there to gauge the present transition?=3D20
Why do you expect the adoption of DTV to take place "overnight"?
We know from past history that people don't care that much about =3D
television
picture quality so long as they can get the information they want.
The problem with today's situation is the poor CEA definition of what =
=3D
constitutes
a DTV set. It's pretty loose in that there's just the requirement of the
ability to "display" 480p or 1080i.
The reason they did this was to be able to inflate the statistics of the =
=3D
number of=3D20
"DTV" sets that have been "sold."=3D20
Another problem: They count sales to dealers,=3D20
not sales to consumers.=3D20
Misleading to say the least.
By this same (?)logic I can claim a VHF only set is actually a VHF/UHF =
=3D
set because=3D20
it is capable of receiving UHF broadcasts by adding a UHF =
converter,=3D20
the original "set top box"!
So I find it pretty rediculous that because it meets the CEA's technical =
=3D
definition=3D20
of being able to "deal with" and display 480p and 1080i, an early B&W Tv =
=3D
from 1949
can be called a "DTV" set.
The tail is really wagging the dog on this one.

And again I ask, why is the 10 year mark important to you when comparing =
=3D
against=3D20
the DTV transition which is isn't yet at the 8 year mark?
