Yes, a web image search turned up a 3-button variant. The only one I'd ever seen was a four-button version, though. It lingered around my aunt's house long after the old TV was gone. I guess it became a conversation piece, like the gray plastic donkey that dispensed cigarettes from its rump.
I don’t recall the separate button (on the three button version). But a search did show a 4-button with all white buttons (not the yellow one). I don’t recall having a yellow button on ours.
I wonder what our kids will be talking about in 50 years? I know some are probably not even familiar with music on CD’s anymore!
Heh. My radio is up on a shelf above my desk just out of reach. When I get a phone call I turn the radio off with a ruler!
