And Sun Microsystems Inc is betting on its Reduced Instruction Set SPARC microprocessor to propel it into the transaction-intensive business market with a 50 MIPS departmental processor likely to be built around the ECL implementation of the SPARC chip under development at Bipolar Integrated Technology Inc of Beaverton, Oregon. Computer Systems News hears that the Mountain View, California company is betting on an implementation of IBM’s Systems Applications Architecture and a distributed relational database, plus a simple-to-grasp user interface for Unix, to keep up the growth momentum that has taken it to $537.5m sales in 1987 from $8.7m in 1983. Fruits of the ambitious development effort, pitched against IBM’s 9370 and Silverlake, are expected around 1990.
