FACOM 230-10

This was a small computer announced by Fuji Tsushinki Manufacturing Corporation (currently Fujitsu) in March 1965. It was developed primarily for economy (cost per day in the minimal configuration was 10,000 yen per day) and ease of use, and it extended the base of computer users. The FACOM 230-10 had capabilities not available with other machines at the time (such as "kana"-capable COBOL, sorting capability, software paging, and expansion using the modular "building block" system), and it was widely used not only for small-scale office computation, but as a branch computer for mid-size and large computers. After it went on sale, it became explosively popular.
