Sequent Computer Systems Inc, Beaverton, Oregon, has added a mid-range Symmetry S16 to its range of transaction processing systems, and has come up with a new version of its Dynix Un ixalike operating system which is claimed to support a range of industry standards. The S16, with from two to four Intel 80386 processors is rated at from 10 MIPS to 30 MIPS depending on configuration and can deliver up to 47 transactions per second. Priced at $50,000 and upwards it is compatible with the rest of the Symmetry line, has from 8Mb to 80Mb memory and from 316Mb to 2.5Gb disk. The Dynix/ptx operating system, which also runs right across the range, is claimed to be X/Open-, Posix- and AT&T System V Interface Definition-compliant. The machine includes a parallel version of Streams for symmetric multiprocessing, and support for AT&T’s Multi-National Language Supplement release 3.2.
