Computer twenty years ago (like the Commodore and Atari) are the tools of the trade of a large community of composers, which is recognized under the label of music '8-bit 'and consists considerable amount of tunes using these antiquated technologies. is very wide community of enthusiasts who gather around the recovery and reuse of these old equipment, often modifying them to exploit their pioneering to the bone and its special characteristics. In this sense, one of the 'most brutal cannibalization of a home computer for musical purposes is MIDIBOX SID , in which a Commodore 64 of the first series has been transformed into a real independent synthesizer with lots of MIDI interface, able to exploit the famous 6581 SID sound chip with a recognizable sounds even many years later.
