From the README
Playing Computer Music via an AM Radio on Computers Like the Altair, IMSAI, PDP8, Sorcerer, TRS80, etc in the 1970s This repository was written as a historical book-end to my 10 year fixation with computer music synthesis design, with this short and simple summary focusing on the generation of rudimentary computer music played through an AM radio in the mid to late 1970s via RF noise emitted by the CPU. Unless you were a business user who could afford a very expensive S-100 system running CP/M on 1 or 2 floppy drives then there wasn't very much that a "home accessible computer" could do other than (drum roll please!) play computer music.
