Total Impact Announces PowerPC G3 Multiprocessor PCI Board And The
Multi-Board PowerBox System

FOR IMMEDIATE RELEASE

CAMARILLO, California, August 4, 1998 — Total Impact today announced the
Total Power G3, a PCI based multiprocessor application accelerator using up
to four PowerPC G3 microprocessors delivering up to 1200 megahertz of
computing power.

The Total Power G3 system is equipped with 1, 2 or 4 PowerPC G3 (a.k.a.
PowerPC 750) microprocessors operating at clock speeds of 233, 266 and
300MHz. The board supports up to 512 megabytes of Synchronous DRAM and each
microprocessor is available with 512Kb or 1 Mb of Level 2 dedicated
backside cache. The Total Power G3 also has a private PMC (Peripheral
Mezzanine Connector) site that allows direct connection of high-speed
communication modules such as Firewire, Ethernet and SCSI.

The Total Power G3 is available with both a 32 and 64-bit PCI bus interface
and is compatible with Windows NT and Apple Power Macintosh computer
systems. Multiprocessor software libraries and developer tools are
included.

PowerBox

Total Impacts PowerBox allows up to ten boards (or 40 processors) to be
used in a PCI based expansion system to further enhance the performance of
a single application or multiple applications. The PowerBox connects to a
Windows NT or Apple Power Macintosh system via a high speed PCI card and is
available in a rack mount or tower configuration. Multiple PowerBox systems
may also be used together for compute intensive applications.

“This type of performance has not been available on the desktop,” said Brad
Nizdil, Total Impacts President. “1.2 Gigahertz is a lot of performance
for a single board and we can increase that performance 10 fold at an
affordable price with the PowerBox. We have also made it very easy for
software developers to access this power without completely rewriting their
applications” he added.

Total Power G3 systems start at $1,600 and PowerBox systems start at
$15,000. Educational, government and OEM discounts are available.

Formed in February of 1995, Total Impact designs and markets advanced
multiprocessor computing solutions for desktop computer systems.
Additionally, the company provides engineering and custom design services.
The companys products are available through a worldwide network of
authorized resellers, distributors and system integrators.
