IRVINE, CALIFORNIA. August 13, 1998. Sonnet Technologies, the leading
manufacturer of performance upgrade products for Apple MacintoshTM
computers, introduced two new models in its line of CrescendoTM G3
processor upgrade cards for PCI Power MacintoshTM Computers. The new
Crescendo G3 upgrades, based on the latest PowerPCTM G3 (750) processor
technology, set new price performance standards for high-end processor
upgrades. The new cards will be available in the following configurations:

Crescendo G3 - 333 MHz with 1MB 2:1 ratio backside cache.
Crescendo G3 - 360 MHz with 1MB 1.5:1 ratio backside cache.

The 333 MHz and 360 MHz models, geared for high-end, performance-hungry
applications, produce impressive MacBench processor scores of 1150 and 1300
respectively - up to 722% faster than the original system.

Consistent with the first series of Crescendo G3 upgrade cards, the
Crescendo G3 333 MHz and 360 MHz have been designed to be universally
