Palm IIIx

The Palm IIIx also had a 16 MHz Motorola DragonBall EZ CPU that is faster, along with claims to be more efficient, than the 16 MHz Motorola DragonBall CPU found in all previous Palm models.

The Palm IIIx featured a new inverse electroluminescent backlight that illuminated the screen text instead of the screen background.

The Palm IIIx also featured an expansion slot inside of its casing.

This slot could accommodate a 3rd party upgrade card and expand the Palm IIIx's functionality or storage ability.

This model suffered from a design defect in its CPU wherein the date would often fail to change at midnight, especially when the batteries were fresh.
