I’m impressed.

My parents had an appliance/electronics shop when I was growing up and they took used items on trade occasionally. Someone turned in one of those zenith sets and I actually got to use that remote. Bear in mind we were well into the age of infrared remotes by this point (late 80s).

It was definitely interesting and I think I could just distinguish the difference between the sounds of the buttons.

There was a YouTube documentary where a dude tracked down the location where this photo was taken.
