Sharp Zaurus
The Sharp Zaurus is the name of a series of Personal
Digital Assistant (PDA) made by Sharp
Electronics. The Zaurus was the most popular PDA during the 1990s
in Japan
and was based on a proprietary operating
system. The first Sharp PDA to use a variant of the Linux
operating system was the SL-5000D.
Zaurus
History
In September of 1993,
Sharp introduced the PI-3000, the first in the Zaurus line of
PDAs. Featuring a black and white LCD
screen, handwriting recognition, and optical communication
capabilities among its features, the Zaurus soon became one of
Sharp's flagship products.
The PI-4000, released in 1994,
expanded the Zaurus' features with a built-in modem
and facsimile
functions. This was succeeded in 1995
by the PI-5000, which had e-mail
and mobile
phone interfaces, as well as PC linking capability. The
Zaurus K-PDA was the first Zaurus to have a built-in keyboard in
addition to handwriting recognition; the PI-6000 and PI-7000 in
brought additional improvements.
During this time, Sharp was making significant advances in color
LCD technology. In May of 1996,
the first color Zaurus was released; the MI-10 and MI-10DC were
equipped with a five-inch color thin-film
transistor (TFT) LCD screen. This model had the ability to
connect to the internet, and had a built-in camera and audio
recorder. Later that year, Sharp developed a forty-inch TFT LCD
screen, the world's largest at the time. In December, the
MI-10/10DC Zaurus was chosen as the year's best product by
Information Display Magazine in the United
States.
Sharp continued to make advancements in display technology; the
Zaurus gained additional multimedia capabilities, such as video
playback, with the introduction of the MI-E1 in Japan in
November of 2000.
The MI-E1 was also the first Zaurus to support both Secure
Digital and CompactFlash
memory cards, a feature which would become standard on future
models as well. The MI series' popularity propelled it into the
U.S. market, renamed the SL series, the first of which was the
SL-5000D "developer edition." This was shortly
followed by the SL-5500; both used an embedded version of the Linux
operating system.

software
With the switch to the Linux operating system the Zaurus became
capable of running variations of a wide variety of proprietary
and open
source software, including web and FTP
servers, databases,
and compilers.
Some developers have created an open source environment for the
Zaurus called OpenZaurus,
which uses the Opie
graphical
user interface and is designed for the power
user, but it does not include the proprietary software which
is distributed with the Zaurus.
