LEADING HARDWARE AND SOFTWARE COMPUTER VENDORS OPEN CENTER TO ACCELERATE PEX MARKETPLACE

            LEADING HARDWARE AND SOFTWARE COMPUTER VENDORS
               OPEN CENTER TO ACCELERATE PEX MARKETPLACE
    RICHARDSON, Texas, Feb. 25 /PRNewswire/ -- Nineteen technology companies are opening the first PEX Interoperability Center (PEX-IC), located at Convex Computer Corporation's headquarters outside of Dallas.
    The companies include Advanced Visual Systems Inc., Convex, Data General Corp., Digital Equipment Corp., Evans & Sutherland, Fujitsu Ltd., Hewlett-Packard Company, IBM Corp., Ithaca Software, Kubota Pacific Computer, Inc., Liant Software Corp., Media Metrix Inc., MIT X Consortium, Network Computing Devices, Inc., Oki Electric Industry Co., Ltd., OMRON Corp., SHOgraphics, Inc., Sun Microsystems, Inc. and Tektronix, Inc.
    Distributing graphics information -- in often incompatible computer environments -- is becoming more critical to computer users.  The introduction of the X Window System in 1985 allowed 2D graphic images to be shared among multiple users working on different vendors' computer systems.  However, 3D graphics transfer was not possible until 1991 when the PEX protocol was introduced.  PEX, an extension of the X Window System, allows 3D graphics to be distributed over networks of heterogeneous computer systems.
    "Everyone gains by accelerating the acceptance of the PEX standard and that's the primary goal of this center," said Curt Wozniak, vice president of engineering at Sun Microsystems.  "With such a center in operation, vendors ensure interoperability and end users gain confidence that PEX is truly functional.  Both hardware and software vendors can test a broad range of products at one time in one place, which helps speed time to market, increases quality and reduces development costs."
    The new center will serve as a PEX interoperability testing site, with participation open to all vendors of PEX-based hardware and software products.  Vendors who contribute and maintain up-to-date hardware and software at the PEX-IC may participate in testing activities at no charge for the first year.
    "We volunteered to host the PEX-IC at Convex because of our belief in the open computing environment and our support of enabling standards and technologies," said Robert J. Paluck, chairman, president and chief executive officer of Convex.  "As a distributed graphics protocol, the PEX technology allows users more flexibility in the highly networked computer environments of today."
    PEX allows a user to create windows on display devices that take advantage of the 3D performance features built into the hardware.  Since PEX is an extension to X, all of the X-based applications and environments that the user relies on today will be available on PEX capable systems.  PEX also reduces network overhead significantly by providing a communications protocol that transmits only the changes made to 3D graphics structures, not the entire structure.
