The Commodore 64 has always been known for its outstanding sound chip. The SID (Sound Interface Device) gives the c64 its trademark sound and is still impressive today. Many people still use the SID in their hardware projects. One such person is Gavin Lyons, who thought the c64 would make an incredible portable Synth, so he turned his Breadbin into one on a shoestring without much bother. Using an SD2ISEC, ARM2SID, an LCD screen and some knobs, he managed to make quite an impressive transformation.
