An enhanced series derived from Fujitsu's mid-size FACOM M-100 Series. The four mid-size general-purpose computers (FACOM M-130F, M-140F, M-150F and M-160F), which pointed the way to the 1980s were announced in April 1979. These FACOM M-100 Series F models had support for the "Japanese processing Extended Feature" (JEF) which made it easy to handle Japanese in the same way as alphanumeric characters and kana. It achieved excellent cost-performance through early adoption of the latest technology -- using state-of-the-art 64Kbit MOS memory throughout main memory units, and 6,000 or 1,500 gate MOS LSI for logic elements. Fujitsu changed its approach from existing "cost-performance first" to easy-of-use in system operation as well as cost-performance to enable direct use by end users. Actually, automated features like automatic power on/off and automatic IPL capability were provided.
The high-end model, the FACOM M-170F, was announced in October 1980. The 1,000th machine was shipped in February 1981. It became Fujitsu's best-selling model.
