It didn’t take Nippon Steel Corp, partner of Concurrent Computer Corp and Supertek Computers Inc and a reseller of Sun Microsystems workstations in Japan, long to make up its mind to get into the US personal computer market. In July, it said it was considering such a move (CI No 1,477) and yesterday it announced formation of Librex Computer Systems Inc in San Jose, California to manufacture and market a broad line of computer products under the Librex name. Next quarter, the new company plans to come out with 80286- and 80386SX-based notebook computers that will rival products produced by current industry leaders, it says. The new firm will get design help from the company’s Electronic Information Systems Division back home in Japan, and manufacturing, operations, sales and marketing will be planned and implemented from San Jose – and a research and development capability will also be established shortly in the US.
