The Commodordion is an 8-bit accordion made from Commodore 64s, floppy disks, and gaffer tape. The instrument has a unique keyboard layout and uses a custom application to play chords and loops. The project's creator spent three and a half years working on the Commodordion, which has some ergonomic flaws, particularly straining the left wrist and arm. Despite its limitations, the instrument is a remarkable example of creative experimentation with old technology.
