Yes. It's called the "VideoTurtle." (What follows comes from a Video Turtle advertisement.) The VideoTurtle is a product that converts your RGB signal, known as TV RGB-15.75KHz scan rate for NTSC, into S-Video! S-Video is an enhanced form of TV with better clarity and resolution than the "TV" we are all familiar with. With your computer, the VideoTurtle, and an S-Video equipped TV, you get equal or better display quality, than your old RGB monitor. Not only that, you get a much bigger and eye-pleasing display, and a TV to boot! The VideoTurtle, from Turtle Enterprises, can be purchased for $149.95 from one of it's authorized distributors, such as Tex Comp Ltd. To order all 1- 800-846-3474.
