SDS Sigma series
From Computer History Wiki
The SDS Sigma series from SDS was a family of 16-bit and (later) 32-bit computers. They were intended for use partially or wholly in real-time settings, but also provided time-sharing and batch processing facilities. The Sigma 6, 8 and 9 were all produced after the merger of SDS and Xerox (forming 'Xerox Data Systems') in March 1969.
A Sigma 7 at UCLA was the first computer connected to the nascent ARPANET.
