Rather surprisingly, Omron Tateishi has beaten the five majors to come out with the first commercial version of a standard Sigma project workstation. The SX9100 runs the Omronix implementation of the Sigma operating system, which is thinly-disguised Unix System V with Berkeley extensions, and is built around the 68020 with 4Mb expandable to 32Mb. Prices go from $13,800 for the low-end Model 10 to $28,000 for the Model 70 file server, and Omron looks to sell 1,000 in year one.
