Look at this 70s set....

www.totalrewind.org/revolution/R_cart.htm

She has a built in video recorder,etc......

I wonder what kind of tube that is?

I'd certainly like to have one for my stash.

I reckon the CRT is just your standard 25V. The chassis could be a tube hybrid, like that 1972 Sears that sat on eBay for ages.

Anyone here would love to get one of them. Probably the
rarest set except maybe the $10,000 Sony 26".

Not so rare that you young whipper-snappers never seen
is the Sylvania consoles with a built in slide adaptor.
It turned out to be "troublesome" so in the end they
were sold off as TV's only, slide section as-is. Dont
remember chassis ## but it was most or all tubes,
late 60's IIRC

I'd take the Sears over the Sony anytime.

What's does the Sylvania slide adapter do?

I dont remember the tech details as they were not fixed.
You had a carousel ( or was it a box ?) just like a slide
projector. It converted the slides to show on the CRT. Quite
advanced at the time. Saves the grief of getting out the
screen, projector & waiting til dark to see your pixs. Only
down side (?) is the kids couldnt make shadow shows
using the TV.
My OM took only slides all his life but watching them was a pain.
He even had a stereo camera that took drop dead awesome
pixs even by todays standards. That was for special pictures
due to the cost.

I believe that the 10K Sony was a 30 inch... huge for a CRT at the time (mid 80s?) .

Here is a thread about another film/tv combination:

Fun stuff for sure!

They also had a cassette player in there for slide function. Probably used for narration. They might have had a tone signal on the tape to advance the slide tray or caraselle.
I only saw one. The yoke was bad for the spot scanner and it was scrapped.

Ya know...With the right slides that Sylvie could be it's own test pattern generator.

KV-3000. I've got one with the matching optional equipment cart, if anyone is interested.

Ah yes, Cartrivision. There have been several discussions of that system here over the years. Look in the Magnetic Tape forum for more.

It looks reasonable for live source material (30 frames / 60 fields per second), which comes out rendered somewhat like a movie. But film material (24 fps), which is normally transmitted in analog as 3/2 pulldown (each movie frame shown by alternating 3 fields / 2 fields) results in a whole movie frame being missed four times a second (ratio of 20/24), which results in very strong jerky sort of motion rendition. The commercially recorded movies for Cartrivision used blended movie frames 4 times a second so two movie frames would be blurred together rather than missing one - still rather poor, but acceptable, especially if no one ever pointed it out to you.

They showed potential partners the results with and without the blending. The main example was from The Graduate, a scene where Dustin Hoffman is hesitating to go through a revolving door because of people coming out. Without the blending, the door seemed to jump back and forth instead of rotating in one direction. In the lab at Motorola, we happened to record a film commercial for a golf resort. The golfer made his putt, but the ball disappeared just before dropping in the cup. Everyone noticed that without being prompted.

The 1.33:1 TV screen, plus nominal overscan of probably 10% minimum, cut off a lot of a 1.5:1 35mm slide. trying to use a vertically oriented slide was even worse. At the time, no one would have accepted black bars at the top and bottom, since that would usually prompt TV owners to make a service call, thinking their picture had shrunk. No one wanted those kinds of calls within the warrantee period. So, the user saw a lot less of the slide than when projecting them the normal way.

we saw one of these units in a very affluent part of columbus.the picture was ok but nothing that made you want to be buy one.the tv itself had a nice,sharp picture but the video tape wasnt very good.watchable but a little blurry.expensive!we were there on another set but the owner was proud of her investment.she told us that this was the future and she got on early.she was right but i personally would have waited.
