More Composite Monitors
In addition to RF television output, many early home PCs supported composite-video monitors (shown here) for a higher-quality image. (The Commodore 1702 also offered an alternative, higher-quality display through an early S-Video connection.) As the PC revolution got into full swing, computer makers (Apple, Commodore, Radio Shack, TI) began to design and brand video monitors--both monochrome and color--especially for their personal computer systems. Most of those monitors were completely interchangeable.
