In this video I take a look at a multimedia educational format from the 1970s, the 3M Sound Page (AKA Ricoh Synchrofax)
UPDATE
I’ve seen a few comments where the assumption has been made that this device was still in use as an educational tool in the 1990s. I think this is highly unlikely. Here’s my take on this – if you’ve ever gone to school, you’ll know that they rarely throw anything away. I know in my school there were things in storage cupboards that hadn’t been used in decades. My theory is that this was used in the 1970s and then stored away until being discovered in the 1990s by some mischievous children who liberated it and used it to record music off the radio (over the top of the old teachers programmes).
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.

A lot of people may be too young to know that some pipe organs could play paper music and it is hard to find information since a lot of it is old.
