The '''REX 6000''' is an ultra-thin [[Personal Digital Assistant]] (PDA) produced by [[Xircom]], and later [[Intel]], from about 2000 to 2001. The REX may be synchronized by inserting it in a host [[Personal computer|PC]]'s PCMCIA/PC-card slot. Docking stations were manufactured for connection to hosts without PC card Type-II slots, which allows the REX to be connected via a [[Universal Serial Bus|USB]] or [[serial port|serial]] connection.

The REX 6000 is the successor to the [[Franklin Electronic Publishers|Franklin]] [[REX 5000]], with a notable difference being the addition of a [[touch screen]].<ref name="PCMag0010206">{{cite web|url=https://uk.pcmag.com/xircom-rex-6000-micropda/31851/review/xircom-rex-6000-micropda | title= Xircom REX 6000 MicroPDA|publisher=PC Mag UK|first=Marge|last=Brown| date=6 February 2001}}</ref> In addition, it is possible to remove and install executable code (including both custom applications and the [[operating system]] itself).  As with the earlier models, the REX 6000 hardware was developed by the [[Citizen Watch Co., Ltd|Citizen Watch Company]] of [[Japan]], marketed as the "DataSlim-2".  The firmware for previous REX models was written by [[Starfish Software]], but the REX 6000, though modeled on previous versions, included a complete re-write of the firmware.

The REX 6000 does not support [[handwriting recognition]] and to enter data, a [[virtual keyboard]] is used. The standard REX 6000 has an [[United States|American]] keyboard layout, although [[Third-party developer|third-party]] software allows for other keyboard layouts. The pre-installed software for the Rex consists of the following:

* [[Calendar]]
* [[Address book]]
* To-do list
* [[Notebook]]
* [[World clock]]
* [[Calculator]]

Third-party software ("add-ins") include games, painting programs, [[spreadsheet]]s and replacements or improvements of the pre-installed software. Most third-party software has been developed in spare time by interested users using customized versions of the [[Z88DK]] [[compiler]] or the [[Small Device C Compiler]] (SDCC).

The earliest release of the REX 6000 had 1&nbsp;[[Megabyte|MB]] of [[flash memory]], while later releases doubled this to 2&nbsp;MB. (Earlier REXes stored user data in [[RAM]] with the operating system in [[Read-only memory|ROM]].) The REX has 32 [[Kilobyte|KB]] of RAM, but only 12&nbsp;KB is available for application developers. It uses a 4.3&nbsp;[[Megahertz|MHz]] [[Toshiba]] [[microprocessor]] compatible to the [[Zilog Z80]], has a 240 × 120 [[pixel]] [[monochrome]] [[Liquid crystal display|LCD]], and is capable of providing beep sounds to deliver alarms and reminders. The REX 6000 is powered by two button-type CR2016 [[lithium]] cells.

Around 2002 Intel acquired Xircom and subsequently discontinued this product line.
