This is a six-foot S-Video cable for a Commodore 64 or 128 (40 column only). S-Video ("Separate" video, named for the separation of the Chroma and Luma signals) results in a higher-quality, sharper image than Composite, since there's no reduction of clarity by combining the C/L signals. The cable includes mono sound. Before you order this cable, make sure your monitor or TV has the connector pictured above. If you have any questions, don't hesitate to send me a PM.
Thanks, Rich
