Fujitsu Ltd yesterday unveiled its first computer built around its G-Micro-32 Tron microprocessor in the shape of a fault-tolerant communications processor, the Sure System 2000, aimed at banks and financial institutions setting up 24-hour-a-day global trading systems. It can also be used in Fujitsu’s mainframe environment as a communications domain. It runs a proprietary operating system called SXO, supports up to 320 19.2Kbps lines, handles Open Systems Interconnection, IBM SNA, TCP/IP and Japan Chainstore Association protocols, and can be used with non-Fujitsu hosts. The microprocessor is supported by 100,000 gate CMOS arrays and uses 4M-bit memory chips, and the machine rents for $9,600 to $21,071 a month. The company looks to sell 2,000 over the next three years, 500 abroad.
