【Oki Electric Industry】 OKITACsystem9 K Series

The OKITACsystem9 K Series, announced by Oki Electric Industry in 1980, was the leader in achieving total conversion to kanji (Chinese characters). In the office computers of the time, only the screen display had been converted to kanji, and kana was dominant in data entry and document printing. With the OKITACsystem9 K, it became possible to perform tasks such as kanji input using a special-purpose book, and document printing with a kanji printer. Messages from the operating system were also displayed in kanji, thereby eliminating confusion for Japanese readers.
