PowerBook 520

The 500 series was the first PowerBook design with a trackpad in place of a trackball, built-in Ethernet and stereo speakers. It had two battery bays, a full-size keyboard with function keys, and a processor on a removable card that could be upgraded to PowerPC. The 520 was the entry model, with a 25 MHz 68LC040 and a 9.5-inch passive-matrix grayscale screen at 640×480.
