Fujitsu has also converted its Aristown geographical information system, which currently runs on its M series mainframes and G series workstations, to the S series workstations that it buys OEM from Sun Microsystems: the S series version of the software supposedly can do high-speed geographical retrieval at 10 times the speed of the mainframe system, and provides strategic information system functions through linkage with relational databases, statistical unit conversion and statistical mapping; Fujitsu is selling the system for prices ranging from $24,000 for a basic system to $78,000 for a high-end version; it hopes to sell 500 over three years.
