Zenith 13" CCII space command portable

[drh4683]

I was looking a little further into that 13" zenith CCII I picked up at the estates last Saturday. I wanted to determine exactly what remote went with it. I figured it used the space command 100 (the single button clicker) as I have a 1978 brochure which has a photo of the SJ-1321W, it looks IDENTICAL in the brochure the set I have, and the 1978 model incicates that it is equipped with space command 100. Considering my set is near exactly the same, but a model SK-1321W, I assumed it also would use the space command 100... Technically, its a 1979 model, but was assembled in March of 1978. Unfortunately, I don't have a 1979 brochure, and even if I did, I doubt Zenith would be advertizing the Chromacolor II sets as the system 3 was the big thing since they introduced it for many of the 1978 models. I tried the set out with my space command 100 remote yesterday and I found out it was muting the sound....that means it has more than one function and is NOT a space command 100. So I decided to try out a space command 600 remote and found I could change channels left and right, the mute worked, and then volume could be stepped, but it would not turn the TV off. So the process of elimination tells me its not a space command 600 either, as if it was a four function remote, the volume stepper would have eventually turned the set off. That being said, this set must have used an electronic remote that had a designated ON-OFF button. The problem is, I have no idea which remote this set used, and I know zenith had about 3 to 5 variations of the electronic ultrasonic remote in the late 70's into the early 80's that all looked quite similar. Some had the chromacolor logo, some didn't, some had a different arrangement of the same buttons, etc. I seem to fall short on any data for this model, I don't even have service manuals that covers this model. Can anyone shed some light on this? Anyone have a '79 brochure or service manual that MIGHT have this particular model in it? This is all in hope that it indicates a remote model, or at least a picture.
