Applications for Patriot Scientific's Microprocessor More Than Double At Key Strategic Partner; GENROCO Expands Use of PSC1000 for Storage, Digital Video Solutions.

SAN DIEGO--(BUSINESS WIRE)--Nov. 8, 1999--

Patriot Scientific Corp. (OTCBB:PTSC) Monday announced that applications for its powerful PSC1000(TM) microprocessor have more than doubled in the past 12 months at a key strategic partner, GENROCO Inc. (OTCBB:GRCI).

GENROCO is a world leader in Storage Area Network (SAN) technology and a pioneer in the development of a new generation of Digital Video Broadcast (DVB) adapter cards. GENROCO also recently formed a subsidiary, VideoPropulsion Inc.

"A year ago, the PSC1000 was powering three GENROCO product applications," noted Jim Lunney, Patriot's president & chief executive officer. "As of today, that number has more than doubled, with the chip now an integral part of eight different storage and digital video broadcast product solutions. These latest applications underscore, once again, our microprocessor's extraordinary flexibility.

"Our partnership with GENROCO, both in current and future applications to be announced, makes us very proud. It also reinforces the viability of the PSC1000 as our new funding enables us to move aggressively ahead in marketing this advanced technology," Lunney said.

Patriot's expanding partnership with GENROCO comes at a time when the Wisconsin-based high technology manufacturer is growing rapidly. Three weeks ago, it announced the creation of a wholly owned subsidiary -- VideoPropulsion Inc. -- to better focus on its digital video business.

"We believe the formation of VideoPropulsion is a great opportunity for our organization's customers, shareholders, employees and vendors to reap the benefits of brainpower directed into two of the most exciting businesses in the new millennium," said Carl A. Pick, GENROCO's chairman, president & chief executive officer, who also will serve as chairman of VideoPropulsion. "The spin-off leaves GENROCO free to concentrate on its core SAN market while creating an entity fully focused on the emerging digital television industry."

Systems using VideoPropulsion DVB hardware and software will soon provide the infrastructure which will allow consumers to use their TV sets for interactive services such as e-mail, home shopping, Web browsing, IP telephony, and other Internet applications. Though volumes for DVB have been relatively low to date, the market is expected to soar as tens of millions of digital set top boxes find their way into homes over the next few years and interactive digital television services begin to roll out.

VideoPropulsion customers have been developing a wide variety of applications, such as video on demand (VOD), for the company's DVB controllers since 1995. Product offerings have grown in sophistication and are being repeatedly selected as the highest performance, lowest cost per video stream on the market today. "The good news for Patriot," observed CEO Jim Lunney, "is that the majority of products GENROCO and VideoPropulsion are developing to meet their customers' needs share a common heritage: made by GENROCO, powered by Patriot."

Founded in 1987, Patriot Scientific Corp. designs, markets and manufactures: the PSC1000, based on the patented ShBoom technology, a 32-bit microprocessor targeted at Java and Internet appliances as well as the traditional embedded systems markets; high-performance ISDN Basic Rate and Primary Rate products for digital communications and ground penetrating radar.
