Fujitsu Ltd has developed terminal emulation software so that the Sun Microsystems Inc workstations it buys OEM can be used as terminals to Fujitsu mainframes: as well as making it possible to connect the Suns in networks along with Facon mainframes and its proprietary G-series Unix workstations, the emulation software is designed to distinguish Suns bought from Fujitsu from those from the likes of Toshiba Corp, which markets the Sun-3 as the AS3000; Fujitsu has a long prospect list for its Suns, and is emphasising financial markets such as dealing systems, as well as laboratory automation, and engineering.
