This machine was a mid-size computer for office use, modeled on the RCA301 made by RCA (a technology partner of Hitachi) and produced domestically in Japan. With the standard system, it had a cycle time of 7É s (1É s = 1 microsecond = 1 millionth of a second), and a memory capacity of 20,000 or 40,000 characters (1 character = 6 + 1 bits). The first machine was delivered to the Kanagawa Prefectural Government Office in 1962, and it contributed to the rationalization of office work.
