The latest league table (up to July 1992) of the value of the US installed computer base, compiled every six months by La Jolla, California-based Computer Intelligence Corp, includes a Unix machine in the top 10 for the first time, among the IBM Corp and Amdahl Corp mainframes, AS/400s and Cray Research Inc Y-MPs. Hewlett Packard Co’s HP 9000-800 series, first introduced in the second quarter of 1986, creeps into the table at number nine with an installed base valued at $1,168m, which is accounted for by a total of 9,730 machines, up by 4% since January. Next on the list is the NCR Corp Tower at number 16, launched way back in 1982, with 53,000 machines installed, worth $746m, declining at 9%. AT&T’s 3B2, the only other machine in the top 25, is at number 18, but its $716m share has shrunk 14% since January. IBM’s 3090-600 takes top position, with 850 installations worth $4,080m.
