The Apple IIc Plus personal computer gives you all the most important benefits of the Apple II family - versatility, expandability, ease of use, and software compatibility - in one compact, lightweight, elegantly designed package. In addition, it has over five times the disk storage capacity of previous Apple IIc models, and up to four times the processing speed.

The Apple IIc Plus offers high-quality color graphics, built-in connectors for easy accessory expansion, a full-size keyboard, and a 3.5-inch high-capacity (800 kilobytes) disk drive. A completely self-contained power supply makes the computer highly transportable, and the handle locks downward to provide a stable, inclined keyboard for typing convenience. Naturally, the IIc Plus also offers the ease of use that has characterized the Apple II family since its inception.
