This isn't new at all, far less "the first". The Altair 8800 didn't have any sound capabilities so people used to tune there radios to the clock frequency of the main data bus and feed data to it at frequency's that were modulated by the bus speed. It sounded like crap but it was far from a tuned system and that was back in the 70's. https://www.youtube.com/watch?...
