Help identifying RCA XL-100 year

[Brianito]

Hello!

I've been driving myself mad trying to find the date of release of the RCA XL-100 console television that belonged to my grandparents. I have a picture that I took in 1983 and I wanted to add info about the set and VCR (also an RCA) for nostalgic reasons.

I am able to narrow the window down a bit. My grandfather always bought RCA. He passed away in 1982 and I know he bought the set. My grandparents moved into a condo in 1981. I am not sure if they bought it then or if they had it at their old house, but they did buy it brand new. I'm about 90% sure they had it before moving, so I'm thinking mid-late '70s.

I scanned the picture at a high resolution and it says RCA XL-100 and underneath what could be ColorTrak. It did not have conventional knobs to change channels, just a button (as can been seen in the closeup). The picture controls were behind a thin, tall door on the right of the screen (also in closeup).

Any help would be greatly appreciated. When I stumbled across this forum, I knew this would be the place to ask.


p.s. blacked out screen as it is old home movies
