Users' Choices for RACEway Expanded With Technology Partnership.

BOSTON--(BUSINESS WIRE)--May 28, 1998--At the Real-Time Computer Show in Boston, TEK Microsystems, a leading supplier of high-performance real-time I/O products, announced that it has been selected as the first authorized reseller of Mercury Computer Systems' RACEway interface chipsets and crossbar products.

Under the reseller agreement, TEK will provide custom engineering services and interface chipset products to support third-party designs using RACEway Interlink as a connection fabric. TEK will also support and resell RACEway crossbars, PCI-RACEway bridges, and RACEway P2 Interlink modules.

TEK has been building products and custom solutions using RACEway Interlink and Mercury chipset technology since 1995. "Our experience, combining high quality custom engineering services and RACEway Interlink technology, make us a natural choice for Mercury - and for Mercury's customers," said Andrew Reddig, President of TEK Microsystems.

Since its approval as an ANSI/VITA standard in 1995,RACEway Interlink has attracted substantial third-party support both in off-the-shelf products and as an interconnection fabric used in a wide variety of high performance systems. More than a dozen companies make RACEway compatible products, providing a wide range of off-the-shelf solutions for data storage, communications, I/O and processing functions.

"The success of RACEway Interlink has been driven by the market's desire for true open standards with the vitality of a competitive marketplace of compatible products. By providing our RACEway Interlink technology through third-party resellers, Mercury is making it even easier for users to incorporate RACEway Interlink into their applications - and assuring users that both products and custom solutions will be available from a range of suppliers," said Bob Levine, RACEway Program Manager for Mercury Computer Systems.

TEK Microsystems, Incorporated designs, manufactures and markets a wide range of high-performance I/O products for real-time control, data acquisition, signal processing and instrumentation systems. In each application area, TEK's products combine the highest performance solution available along with unmatched support and ease of integration.

In addition, TEK's emphasis on customizable hardware as a key element of all products provides the flexibility required to provide an optimum solution for a range of off-the-shelf applications - along with the ability to quickly and easily tailor products to application-specific requirements. All of TEK's products are based on open standard bus architectures, including VMEbus, RACEway Interlink, PCI, PMC and IP.

TEK is located in Burlington, Massachusetts and has provided customers with custom engineering services and off-the-shelf products since 1981.

Mercury Computer Systems (NASDAQ:MRCY) designs, manufactures, and markets high-performance digital signal processing computer systems that transform sensor data to information in real time. Mercury's computer systems are used in both defense and medical signal processing applications. In air-, sea- and land-based military platforms, these systems process real-time radar, sonar, and signal intelligence data. In medical imaging, Mercury's systems are embedded within diagnostic devices for modalities including magnetic resonance imaging (MRI), computed tomography (CT), and positron emission tomography (PET). Mercury's systems are typically used in applications that are computation-intensive and require I/O and interprocessor bandwidth not available on general-purpose PC or workstation platforms.

Mercury has also targeted the shared storage market for introduction of new technology that allows multiple users to access files simultaneously. Markets for this technology include the entertainment and broadcast industries, where many users need simultaneous access to large media files. Current products let users share files stored on commodity disk arrays connected to desktop computers by FibreChannel or other high-bandwidth networks.

With headquarters in Chelmsford, Massachusetts, the company has more than 360 employees serving customers in North America, Europe and Asia through a network of subsidiaries and distributors.
