The Santa Cruz-based Integrated Micro Products Inc arm of the Consett, County Durham company has doubled the performance of its Unix-based fault-tolerant computer line with a model using the 50MHz Motorola 68030. The XR 655 is rated at 10 MIPS, double the performance of the XR 650 system and costs $13,000 per MIPS, against $20,000 per MIPS for the new Tandem S-2. System prices start at $130,000. The company sees the XR 655 being used as a front-end to large database systems, and it has teamed up with Pyramid Technology Corp and Oracle Corp to integrate its fault-tolerant machines with Pyramid’s MIServers and the Oracle Corp relational database. The partners see a big future for the combination, particularly telephone sales of financial services.
