powerbook 520 and 520c

The powerbook 500 series were the first powerbooks with the power Motorola 68LC040 CPU (simultaneous with the powerbook duo 280) and were upgradeable to the PowerPC architecture via a swap out CPU daughter card (with the PowerPC and 68040 upgrades for sale).

​

The 500 series were also the first laptop computer to use a trackpad instead of a trackball as a built-in pointing device and the first to have ethernet networking built-in. The model 520 came with a  passive matrix and the 520c with a color passive matrix display with 16bit stereo sound with stereo speakers, had an expansion bay, PC Card capability, and two battery bays.

​

The powerbook 500 series were also the last powerbooks with scsi-harddisc.
