Stratus Computer Inc is moving its fault-tolerant Unix and VOS machines to the Hewlett-Packard Co Precision Architecture RISC from the Intel Corp 80860, but IBM Corp has just renewed its OEM agreement with Stratus, which dates back to 1985. IBM sells the Stratus machines as System/88, but the new contract includes a cross-licensing agreement giving IBM and Stratus some rights to each other’s patents, suggesting that IBM may have designs on developing its own fault-tolerant Unix for the RS/6000. The original OEM agreement was intended to be a stopgap while IBM developed its own fault-tolerant machines.
