FUJITSU K-690Si

These were office computers (small business computers used in offices) from Fujitsu. Fujitsu announced the FUJITSU K-600Si Series (4 model groups and 12 models) in October 1990 as the successor of the FACOM K-600 Series. With the advent of the era of strategic use of information systems, Fujitsu added the Si suffix to its model names, and adopted the slogan "SIS begins with K". In the following year the series was expanded to 13 models, with the addition of the top-end FUJITSU K-690Si Model 30 (4 CPUs).
