NTT History Center of Technologies exhibits the history of telecommunication technologies in NTT group over the past half-centuries since the former Nippon Telegraph and Telephone Public Corporation.

In '50s NTT performed the research and development of computers to improve the efficiency in telephone and telegraph services. MUSASHINO-1B based on parametron elements was one of the most outstanding achievements. Also, CM-1 was the automatic telephone charge calculation system based on parametrons, and following CM-100 was the transistor-based general billing computer system.

As for the last '60 downward, to realize on-line data communication services following the original telephone and telegraph services, the DIPS☆1 research and development project was launched in 1968. NTT had leaded the DIPS joint project with NEC, Hitachi and Fujitsu since 1969.

At the NTT History Center of Technologies, visitors can learn the history of the research and development of computers in Nippon Telegraph and Telephone Public Corporation and succeeded Nippon Telegraph and Telephone Corporation. NTT History Center of Technologies exhibits a collection of historical assets of various computers and peripherals including MUSASHINO-1B (Certified Information Processing Heritage by IPSJ, 1957), DISP-11/45 (Main frame computer in DIPS project, 1982) and magnetic drum/disk memory units.
