Sales flyer for Theatervision front projector. Apparently used a Sony Trinitron receiver and optics to project on a curved screen.

That had to be 1971 or later. They show a Sony VO-1600 which was Sony's first U-matic deck introduced in 1971 (I own one).

I actually have a Sony front projection TV from the late 70s, KP-7220 I think. It has a glass top to use it as a coffee table and it has a curved aluminum screen. Not sure what to do with it.......

mrs dave thomas of wendys fame gave a friend and co worker of mine a similiar set.it had a sony receiver and a sliding base to enlarge the picture.weighed a ton and we carried it up from a finished basement.he sold it on the street.she was a really caring woman and when he expressed that having it would be a dream,she said take it.we did and he got a couple hundred dollars for it.about 8 years later,i was offered a free one and passed.picture wasnt good and heavy.heavy.heavy.

In 1976, those Theatervision units sold for $1995.

Kiplinger's Changing Times Magazine had an article about them in October 1976, and Popular Science had a similar article (more of a how-to) in November of 1977. Both are available on Google Books, full view.

I remembered the PopSci article from my teenage years - I had an ex-hospital Sony 17" set I so wanted to convert, but had no room in my 12X14' bedroom...never did get to build the "Personal submarine" either...:tears:
