INTEQ by Zenith, Anyone had/have one?

[JohnAdams]

I have found no mention by anone else about the INTEQ by Zenith.
I found a brochure while trying to find an 84 Zenith brochure.
Does anybody remember the INTEQ series with the 32 & 35" Invar picture tubes? What year was this?
I don't see the word "Zenith" mentioned anywhere in the brochure. Only the Glenview, IL address gives it away. Plus the cover letter sent by Bill Sims has "Zenith" in minute print at the bottom. There is no date on anything that I have.
"from a 27" to 60" tv, dvd or vcr".
4 crt tv's. A 27, 32, 35 table model & 35 table model. All with Dolby Pro-Logic Sound. 2 projection tv sizes. A sub woofer base for table models, tower surround sound speakers, a dvd player and a VHS-VCR.
Here is a scan of a couple of pages from the brochure.
Has anyone ever seen one of these sets or know what year they were ??????????????
