DIPS 11/5E

In 1979, the research center of the Nippon Telegraph and Telephone Public Corporation (now NTT) began studying the 5E Series as the successor to the DIPS-11/5 Series, and a development plan was launched in August 1982 to raise the processing capacity of information processing system centers, achieve more flexible system configurations, and respond to the need for higher reliability brought on by the growing scale of systems in those centers. The main features were achievement of a highly reliable system with large-scale highly expandable system configurations,higher performance and improved cost performance, and centralization, saving of labor, and automation in operation/maintenance.
