A series of multi-user IBM Personal AT-compatible systems that support Unix, PC-DOS, RM/COS, and Pick have been introduced in the US by CIE Systems Inc of Irvine, California, a subsidiary of the C Itoh Electronics arm of the $80,000m-a-year Japanese trading giant. The two-, six-, and nine-user 80286-based systems are compatible the company’s 68020-based supermicros – but only when fitted with teh 68000-based co-processor that is required to run Unix and RM-COS. The processor speed on the CIES/286 family is switchable from 10MHz through 8MHz down to 6MHz where time-dependent software requires it. The two-user CIES/2286 includes a 40Mb Winchester, 1.2Mb floppy, 512Kb CPU and a system console, and costs $5,960; the six-user CIES/6286 adds a 60Mb quarter inch tape unit and costs $8,085. The nine-user CIES/9286 has 70Mb disk, a 60Mb tape, floppy and the system console for $9,800. System prices vary with the operating system chosen. Memory can be expanded to 4Mb of zero-wait-state memory or 8Mb of conventional extended memory. MS-DOS is included with all models of the CIES/286 family.
