The [[Franklin Electronic Publishers|Franklin]] '''REX 5''', (also known as the “Rex-Pro”, as the “Rex 5000”, and with cosmetic variation as the “Rex 5001”) was one of the Rex line of [[Personal Digital Assistant]]s, each a [[PCMCIA]] [[PC card]] and thus the size of a credit card, built around a [[Toshiba]] [[microprocessor]] emulating a [[Zilog Z80]].  The REX firmware was written by Starfish Software, and the hardware was manufactured by Citizen Electronics.  Earlier models in this line (the Rex and the [[Rex-3]]) had almost no input possibilities except to download data when installed in a host computer or in a docking station; the Rex 5 added a sixth button and introduced a modal input method. (The later [[REX 6000]] again had only five buttons, but included a touch screen.) Further, with 512 [[Kilobyte|KB]] of [[Random Access Memory|RAM]], the Rex 5 had twice the memory of the Rex-3 (which, in turn, had four times that of the original Rex).

The REX 5000 was repackaged by [[Motorola]] as the StarTAC ClipOn Organizer, which piggybacked onto digital versions of their popular [[StarTAC]] phone (as well as some Timeport models), expanding the capabilities of the phone from having a capacity of 100 contacts to 1000, and adding calendar and note functionality.

The REX 5000 and StarTAC ClipOn Organizer, like earlier models of the Rex, utilized [[Starfish Software]]'s [[TrueSync]] for data synchronization. Starfish would later be acquired by Motorola.

The REX 5000 was succeeded by the [[Xircom]] [[REX 6000]].
