Vinyl Code

Back in the day, when fighting music piracy wasn't the primary goal of record companies -- record companies actually liked their customers. Liked them so much, that in some vinyls released in the 1970s and 80s, they included bonus material. The bonus material that came shipped on the rare vinyls were computer code embedded in audio, to run on the Sinclair Spectrum home computer (my first computer was the Timex Sinclair). Some of the code that was secreted on vinyls, included simple computer games. As Kempa.com points out, some of the games and emulators to allow you to play them on your computer, are available. If you missed the gems the first time around, you can still give them a spin.
