The USAC-1010, an origin of some of successful office computer models, was first manufactured in 1963, a time when the use of office computers was just beginning to spread. The USAC-1010, an ultra-small computer (cost: 5.5 million yen or more) at that time, was mainly used for office works of organizations such as local governments and computing centers. This machine was widely used for small-scale batch processing, and it helped contribute to the modernization of the office.
This USAC-1010 allowed easy input of Katakana characters, alphabetical characters, special characters, and other characters from a computer, and was suitable for everyday office work. In addition, by being equipped with a high-speed paper tape puncher and a photoelectric paper tape reader that had previously only been available in mid-size or larger computers, a high processing speed could be achieved by the USAC-1010 despite its compact size.
As a pioneer in civil service modernization, Fujiyoshida City Hall became the first local government user of the USAC-1010. After this, the USAC-1010 was introduced in many other local governments across Japan.
