ZEOS SUBSIDIARY PCTECH DEVELOPS REVOLUTIONARY PCI TO IDE INTERFACE CHIP FOR PCS; LICENSES AVAILABLE, PATENT PENDING IN NEW DEVELOPMENT

 ATLANTA, May 25 /PRNewswire/ -- ZEOS International, Ltd. (NASDAQ-NMS: ZEOS) announces today that its wholly owned subsidiary, PCTech of Lake City, Minn. has developed a new interface chip designed to make low cost IDE disk drives and other Input/Output (I/O) devices to the new Intel (INTC) backed Peripheral Component Interconnect (PCI) local bus standard.
 The new development was announced today at a computer industry trade show, "Comdex," being held in Atlanta. The chip, designated the RZ1000, is fully PCI 2.0 compliant and is designed to reduce the cost and enhance performance of PC systems using the new PCI interface standard, in part by allowing the use of low-cost IDE hard drives while achieving a level of performance not possible with current Industry Standard Architecture (ISA) based IDE interfaces.
 Integrating what were previously several electronic devices into one highly integrated single-chip solution provides a complete PCI to IDE interface fully compatible with existing IDE software and operational commands. Up to four IDE devices can be supported and no special software or software drivers are required for use of the new device with today's PC operating systems.
 Among the other special features of the new chip include its IDEa(TM) port. The IDEa port allows many other standard ISA type peripheral I/O devices to be moved to the PCI local bus at low cost while achieving the performance boosts associated with the local bus/CPU interface. Examples of devices that may be placed on the IDEa port include SCSI controllers, serial or parallel ports and data compression circuits.
 The PCI local bus interface was first announced in June of 1992. It has been gaining considerable PC industry momentum with many new PCI based product introductions expected over the next several quarters. The PCI itself is an open architecture standard designed to eliminate PC performance bottlenecks by providing a high performance, processor independent data path between the CPU and high-speed peripheral devices.
 According to a company spokesperson "The RZ1000 is the perfect match between new PCI chip sets from companies like Intel, and peripheral devices, like IDE hard disk drives, which would not have been able to take full advantage of the new PCI standard. Because we view this invention as important for all personal computer manufacturers we are presently entertaining licensing proposals for the RZ1000.
 "Patent protection is presently pending," the spokesperson added.
 Companies interested in obtaining additional information on the new RZ1000 PCI to IDE interface may contact: PCTech, 980 West Lakewood Avenue, Lake City, Minn., 55041. The telephone number is 612-345-4555. PCTech is a wholly owned subsidiary of ZEOS International, Ltd.
