Charles River Data Systems, Framingham, Massachusetts, is preparing a multiprocessing version, release 8, of its Unos operating system, a non-licenced version of Unix that is nevertheless claimed to be System V Interface Definition- and Posix-compliant. According to Computer Systems News, the new release will also have a Dedicated Auxilliary Processor feature that will enable one processor – out of a maximum of seven to be supported – to be dedicated to a single real-time function. Unos 8 is in beta test and is planned to be generally available by the end of next year. On the hardware front, the company is ready with a 68030 processor board that will be supported in the top two of its three machine models, the desk-top or rackmount Universe 200, the rackmount or tower Universe 400 and the cabinet Universe 600. The new VCP6000 68030 board will join the existing 68000-based VCP1000 – only used in the Universe 200 model – the 68010-based VCP2000 and 68020-based VCP4000 boards; it will initially use a 20MHz version of the new Motorola part, but a 25MHz version will follow in the second quarter, and the processor board has been designed for clock rates up to 33MHz. Only the VPC6000 board and a new VPC4000MP will be usable in multiprocessor configurations. While seven CPUs is the maximum, four will be optimum using the 68020 boards because of local memory limitations. All but the new 68030 processor need a second board for memory man agement. The Universes use a 32-bit VMEbus and are used primarily in real-time transaction and manu facturing applications. Pricing for the new products has not yet been set, but a machine using two VCP4000MPs will be about $23,000, four CPUs will be under $50,000.
