The buttons on Zenith’s original “clicker” remote were a mechanical marvel

This is a most excellent place for technology news and articles.
My aunt and uncle still had a TV with one of these things when I was growing up in the 90s (the 70s version). The buttons had a distinct and satisfying click to them.
There was only one volume button, and and each press would turn up the volume in 3-4 steps and then cycle around to mute. You couldn't turn the volume down without turning it up first. If you wanted more fine control you still had to get up and adjust the volume knob on the set.
I wonder what my aunt and uncle eventually did with that big old box. It belongs in a museum.
