Following its decision to go with AT&T Co’s Unix System V.4 rather than wait for the Open Software Foundation’s OSF/1 offering, Siemens Data Systems has unveiled a series of Intel 80486-based departmental systems running a Unix System V.4-compatible version of its Sinix operating system. The MX300I series has three models, the 300-45 and 300-50, which both use a 25MHz version of the processor and are rated at 20 MIPS, and the 300-60 which operates at 33MHz, and, rated at 27 MIPS, supports up to 54 users. All run Sinix V.40, which the company says is compliant with X/Open Co Ltd’s XPG3 portability guide, and come bundled with the OSF/Motif graphical user interface. The company gave no prices.
