Datapoint Corp, San Antonio, Texas, this week duly announced the 68030-and 68020-based Unix systems that it is buying OEM from Norsk Computer Industri A/S and Scanvest-Ring Data A/S, both of Sandnes, Norway (CI No 859). The machines, launched as the SX100, 200 and 300, will be offered as Unix servers on the ARCnet local area network. The systems will provide transparent access to ARCnet network and its RMS Resource Management System operating system. At Uniforum, the company has been demonstrating the DX200 as a video server to Datapoint’s Minx Multimedia Information Network Exchange visual communication network, which already enables users to switch between full colour, full-motion conference mode and MS-DOS data mode. The DNX line starts at under $20,000 and is rated at from 2.5 MIPS to 25 MIPS: it comes with uninterruptible power supply and mirrored disks for security and integrity. Datapoint reckons that it has an edge in the Unix world, where Ethernet proliferates, because the network bus arbitration scheme of ARCnet means that it can generally handle many times the throughput of an Ethernet local area network.
