Apple Computer Inc, Motorola Inc, Data General Corp and Sequent Computer Systems Inc are all said to be in discussions with Compagnie des Machines Bull SA’s new OEM unit about taking its Pegasus symmetric multiprocessing technology. On offer is the PowerPC architecture, input-output bus, and operating system package. Meanwhile, it looks as if Bull’s high-end Mississippi project is not a cluster of Pegasus boxes after all, but rather a single machine expected to house up to eight of the forthcoming symmetric multiprocessing optimised PowerPC 620s. It will run a version of AIX beyond 4.1 as well as Bull’s proprietary GCOS mainframe operating system. IBM is also expected to resell the machine, which is being talked up as running at 5,000 transactions per second. Mississippi may roll along as soon as October.
