San Jose, California-based Tatung Science & Technology Inc is still very much in the Sparcsystem-building game and has revealed product development plans that include introduction of three new series of MBus-based superscalar systems in the next six months. The new systems include the COMPstation 99, the Super COMPserver and Super COMPstation, each to be priced 25% to 30% cheaper than comparable systems of Sun Microsystems Inc. The systems will offer full binary compatibility and Solaris 2.0 as the operating environment. The COMPstation 99 Superscalar Series in September is to feature up to two 36MHz or 40MHz processors and do 64.7 SPECmarks. The Super COMPserver will follow, using up to four 36MHz, 40MHz or 45MHz processors, eight SBus slots, up to nine drive slots; Super COMPstation will have up to four CPUs.
