Scientific Data Systems
From Computer History Wiki
Scientific Data Systems was an early manufacturer of small mainframes, mostly for scientific/engineering work. They enjoyed some success with the 24-bit 930 and 940, running modest time-sharing systems (many descended from the Berkeley Timesharing System).
Their 32-bit Sigma 7 is notorious for being the first ARPANET host.
They were sold to Xerox and renamed Xerox Data Systems (XDS); Xerox was unable to make a success of the computer business, and XDS was shut down (at a huge loss).
