Insights into the kind of crap 78-rpm records were made of, and other scarce technical infos.
If you’re not sure what ‘a record’ is, or haven’t ever seen one, you’re excused.
Oh, and by-the-way, 78 is the approximate number you get when you rotate a 46-tooth gear with a 3600 rpm motor. (60 cycles per second.)

I just find it really interesting.
My house is full of dead technology like this just because I’m curious or like the aesthetics.
