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).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.

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.
