@BrianRoemmele I always wondered why they didn't make an iPod in form of cassette tape... so you didn't need one of those ugly tape -> 1/8" jack thing.1 reply 0 retweets 2 likes -

Victor, indeed. I saw a patent once that had a power source that used the tape drive motor to power a small generator in a cassette tape for an external speaker device. Ingenious.

Rock, it was 9 volts with good enough amps to drive a 25 watt RMS stereo system. The patent was really more about the small pre IC transistors and capacitor arrangements really high density for the period. I am sure it never got built though.
