This was an office computer (a small business computer used in an office) from Fujitsu -- the successor of the FACOM K-200 Series R Models. Fujitsu announced the 4 model groups and 9 models of the FACOM K-600 Series (K-610 and K-630 Model 10 and 20, K-650 Model 10, 20 and 30, and K-670 Model 10, 20 and 30) in October 1988 as "partners for strategic management" in enterprise management of the 1990s. The features of this FACOM K-600 Series were as follows:
(1) As a "partner for strategic management", the series established 4 support concepts:
-Extension support (covering a wide performance range, field upgrading, and vertical/horizontal linkage)
-Application support (380 types of accumulated business/specialized applications, support by "Application Land" at 15 locations, DSS decision-making support system)
-Development support (Distributed development, high-production tools "CASET" and "YPS", RDB and SQL)
-Customer support (New product information, and providing the latest information through functions like seminars and events)
(2) The top-end K-670 was the first office computer to use a symmetrical multiprocessor employing 2 CPUs
-System performed improved by 2 times over previous levels (Ratio of K-670/30 to K-310R)
(3) Virtual memory address space and real memory address space 2 times larger than previous machines (Ratio of K-670 to K-310R)
-Virtual memory address space was expanded from 64MB to 128MB (later, this was expanded to 250MB with the K-670/40, and 384MB with the K-690)
-Real memory address space was expanded from 31MB to 64MB
(4) Disk access performance was significantly improved with a high-speed disk buffer which used part of the real memory as a disk area
In May 1989 (the following year), Fujitsu added the FACOM K-670 Model 40, the first office computer equipped with 3 CPUs, and thereby expanded the performance range of their office computers. This series developed into the FUJITSU K-600Si Series.
