Composite out being pretty rare on game machines back then? Let's see:
NES - Came with built in composite A/V out
SMS - Came with built in composite A/V out
Genesis - Came with built in composite A/V out
Rare indeed. All of these systems I had a great deal of experience with before touching the Turbo. And yes, all systems RF is limited to mono. To do stereo over RF you would need a license from MTS.
You're right. I was setting me standards way too high. I had absolutely no right whatsoever in being disappointed with the system. Only nit-picking cantankerous old dudes would dare not like everything about the Turbo without exception. I deserve AIDS.
The actual Composite A/V cable for the SMS and Genesis was and is rare though. I never got to try SMS through 'video' until after I got my first Turbo Duo. And for years people had a hard time finding a replacement Duo cable(many still do).
Even by the time I got the Turbo Booster for my TG-16, none of my friends had a TV that accepted composite(we had a nice Sony TV for years).
I also remember RF switches and 'modulators(?)' selling well during the 32-bit generation because of all the people needing to 'downgrade', but I don't remember anyone else trying to upgrade during the 16-bit generation.
Even when I had a black and white TV with RF only, I used the composite hook-up through my VCR mainly so I could route the audio to a stereo. What's funny about black and white is it really seems pretty clear since there isn't any dot-crawl/color bleed and all that. And you get used to it after a few minutes. When I finally got a color TV I had a hell of a time finding one that was good enough. It had to have S-video and I finally found a 20-inch Sony that did. Still have it and it still works great, but I don't use it for gaming anymore. For gaming I have a 20 inch Toshiba (made by Sansui) and all of the game systems except the NES are hooked up via component video. The video is really good, but I worry about the longevity of the TV.
I had like a 12" or 10" b/w TV in my bedroom when I received my first NES. I had so much fun playing SMB on it(I also remember renting and play Dragon Power on it). At the time, I was lucky just to have my own TV at all. Neighborhood kids would come over and we'd all sit around it.
Back then, older color TVs weren't perfect, just as Plasma and LCD TVs aren't perfect now. But man that little b/w TV sure had a nice clear picture.
