The Rex 6000
is an ultra-thin PDA
produced by Xircom, then Intel
, from about 2000
. Its primary claim to fame is as "The world's smallest full-function PDA"
: due to its unusual physical configuration as a PCMCIA
Type-II card (8.57 x 5.40 x .5 cm
; 40 g
), it may be synchronized by inserting it in a host PC
's PCMCIA/PC-card slot.
The Rex 6000 is the successor to the Franklin REX 5000, with the primary difference being the addition of a touch screen. It appears to have been initially developed by the Citizen Watch Company of Japan, marketed as the "DataSlim-2."
The Rex 6000 is available with up to 2 MB of flash memory. It uses a 4.3 MHz Z80 microprocessor, has a 240 by 120 pixel monochrome LCD, and is powered by two button-type lithium cells.
As of 2003, the Rex 6000 retains a devoted group of users and developers.
