The casette tape pictured above is the very first piece of software that Apple ever sold. It’s the Apple I Basic cassette, and it was released in 1976. This piece of software has been extracted from the cassette and turned into an mp3 that’s 38 seconds long.
Some very smart people have been getting extremely geeky with it, and are dissecting it for further study. You can read about that here.
What I did was take the audio file, and turn it into the geekiest iPhone Ringtone in history. Which you can download here.
