Santa Ana, California-based Novadyne Computer Systems Inc, successor company to Microdata and McDonnell Douglas Information Systems in the US, has come out with a line of multiprocessors based on the 88100 RISC from Motorola Inc with hardware sourced from Encore Computer Corp, Fort Lauderdale. The Series XT family runs the company’s Umax, which combines its Reality implementation of Pick with Unix System V, and is designed for 64 to 256 users. It comes with two or four tightly-coupled 88100 CPUs and is claimed to have the industry’s fastest processor-to-memory bus, running at 100Mbytes per second, plus intelligent input-output and both symmetrical and parallel multiprocessing capability by virtue of the multi-threaded capabilities of Umax. The dual-processor Series XT will be available in the US next month, with the four-processor model following in the second quarter. The high-speed M-bus is used exclusively for traffic between processors and memory and a standard VMEbus is used for communications, single or dual SCSI buses for mass storage, and an Ethernet channel for supporting the terminals. Umax supports the Stream input-output interface and Berkeley Fast File System. The Series XT line has from 16Mb to 272Mb memory and up to 6.3Gb disk. No prices.
