SONNET ANNOUNCES G4 DUAL PROCESSOR UPGRADE

SAN FRANCISCO, CALIFORNIA January 9, 2001. Sonnet Technologies, the
worldwide market share leader in processor upgrade cards for Apple
Macintosh computers, announces the first product in a dual processor
product line for Power Mac G4 AGP Graphics (Sawtooth) machines called the
Encore/ST G4 Duet. This card is comprised of dual 500 MHz processors, each
with its own 1MB/250MHz backside cache. Sonnet will ship the first cards in
February for a suggested price of $999.95. With a design that is
plug-compatible with Apples dual processor design, the Encore/ST G4 Duet
will upgrade any AGP Graphics G4 machine to the equivalent of Apples dual
500 system. Power Mac G4 owners will be able to take full advantage of OS
Xs symmetrical multiprocessing, as well as all applications updated by
other manufacturers to support multiple processors. The Encore/ST G4 Duet
integrates seamlessly with all applications. It supports all G4 operating
systems from Mac OS 8.6 through OS X without any additional software.

With Sonnets 100% software compatibility guarantee, the Encore/ST G4 Duet
offers a sensible choice for getting dual 500 MHz G4s. It installs into an
existing machine in minutes for hundreds of dollars less than the cost of
switching to a new machine, and there is nothing else to change, reinstall
or reconfigure. There are no additional file transfers, no software
installations, and no switches or jumpers to configure. Included with the
product is an easy-to-install heat sink adapter that provides effective
cooling for both processors.

Simply Fast
Sonnet products are guaranteed to operate reliably over variations of
machine, time and temperature. All Sonnet Presto, Crescendo, Encore, Tempo,
and Tango cards work in every compatible Macintosh without the need for the
antiquated methods of configuration. The ability to move an upgrade card
from one machine to another without the need to tweak any jumpers or
control panels is a significant advantage to resellers and organizations
that want to maximize their flexibility, while minimizing the long term
technical support requirements. Sonnet cards have unequaled
ease-of-installation and reliability, and are Simply Fast.
