The Apple IIGS personal computer is the most powerful, most colorful Apple II ever made. The Apple IIGS combines the best of the Apple IIc (its built-in accessory ports) and the best of the Apple IIe (its versatile expansion slots) with an interface similar to that of the Macintosh personal computer. It also offers powerful new features, such as high-resolution color graphics, 15-voice sound, and the new 65C816 microprocessor.
