Apple Mouse IIc
Background
Four months after the Macintosh debut, the Apple IIc was introduced with the addition of an optional mouse to manipulate standard 80 column text. The mouse was similar to the Macintosh mouse, though it was in a creamy-beige color that co-ordinated with the IIc's bright off-white case and had a slightly modified design which was sleeker than the Macintosh's blockier shape. It also was uniformly the same color, eliminating the Mac and Lisa's contrasting taupe accents on the mouse button and cable. Unlike the Macintosh, the IIc Mouse shared a dual purpose port with gaming devices like joysticks. In order for the IIc to know what was plugged into it, its mouse had to send the appropriate signal. Despite these differences, it carried exactly the same model number as the Macintosh version. Since the original Apple Mouse IIc was compatible across all platforms, Apple renamed the mouse in 1985 and offered it as an optional purchase for all computers and separate from the Apple II interface card. It featured an updated mechanism and the new uniform rounded cable connector.
