These were the first 32-bit super minicomputers from Fujitsu and Panafacom (currently PFU). In February 1983, the FACOM S-3000 Series was announced by Fujitsu, and the PANAFACOM S-3000 Series by Panafacom, as upper series of Panafacom's PANAFACOM U-1000 Series of 16-bit minicomputers. These machines only differed in their brand name; they were exactly the same product. This S-3000 Series was comprised of two models -- the S-3300 and S-3500 -- and was developed jointly by the two companies by adding minicomputer functionality (direct CPU connection with process control equipment, functions for real-time processing and main memory battery backup capability etc.) to the Fujitsu's FACOM M-300 Series of general-purpose computers. These machines were used in a wide range of fields, including LA (Laboratory Automation) CAD/CAM, FA (Factory Automation), science and engineering computation and communications control.
After May 1990, the brand name "FACOM" was changed to "FUJITSU".
