NEC Corp is determined to get its SX-3 scientific supercomputer established in the US market, and as well as joining forces with ICF Severn Inc, a systems integrator based just outside Washington to bid on a tender for supercomputers from the US Environmental Protection Agency, the company is reported from Tokyo to be negotiating an agreement with Control Data Corp’s Computer Products Group for joint marketing of the machines. NEC currently markets the machines through its HNSX Supercomputers Inc, which was formed as a joint venture with Honeywell Inc but is now wholly NEC-owned; although the company has sold one SX in Canada and several in Europe it has yet to make its first commercial sale in the US.
