The GTE Sylvania console variant is one of the more interesting ones, IMHO. My first reaction upon learning of it was What the h? - it just seemed so odd. I mean, what's a company that makes light bulbs and stereos doing putting its name on a game console? Then again, the video game craze of the late 1970's and early 1980's was becoming a cultural phenomenon.

Hazarding guesses is something that's fun to do, so here's some speculation about this console variant. It's probably the very first one Mattel made, given the marketing materials that have been found so far. Of the three such variants (Sears and Tandy being the others), it is the only one that marketed the original Keyboard Component. As to what the special connection was that got GTE Sylvania to put its name on Intellivision units - you got me. Anybody have some good info on that? Just drop me a line.

Anyhow, below we have the two known flyers from Sylvania. In addition, a service manual is known to exist. I believe the Intellivision Bodega has a copy to download, and IIRC, Frank Palazzolo's 2-Bits Web Site is the original location.

This is a high-quality - and clearly very early - flyer touting the GTE Sylvania Intellivision with an excellent preview of software for the Keyboard Component. It's especially fun to see the Keyboard Component with the GTE Sylvania faceplate on it. Wonder if there were really any like that, or if they just tweaked a photo of a Mattel KC for the pictures? In any case, the Keyboard Component software and info is excellent! Please forgive the scan quality - the actual flyer does not have discolored bands along the edges. It's the fault of the scanner I'm using. (Did this while on vacation.)
This appears to have been a small flyer one would find next to a display or at a check-out. The screen shots seem to be the same as the ones in the larger flyer shown above. Gotta love that 'Power 8 Blackjack'. :-D Nothing like some good ol' human transcription errors to give a cheap laugh. My, what good quality control in the Marketing department! (Many thanks to Jeremy at the Intellivision Gumbo site for digging up his flyer and contributing the scans) If anyone out there has one of these (or any other GTE Sylvania Intellivision literature) available, I'm interested! Just drop me an email!
