MacWeek hears that Apple Computer Inc’s Business Systems Division is working on Unix-based multiprocessors that will initially use the 80MHz PowerPC 601 processor, but aims eventually to use the 604 chips due out in the middle of next year: the machines, rated at up to 400 MIPS, will run native Unix AppleTalk Filing Protocol server software under development within Apple says the paper, and it will run IBM Corp’s AIX 4.1 Unix implementation rather than A/UX; it will be the first Apple model to support Peripheral Component Interconnect will have multidisk RAID, and may include FDDI support; AppleTalk Filing Protocol, however, may not be ready in time for the initial release, in which case a version of AppleShare Pro on top of the portable Mac Toolbox will be used, but that can’t exploit multiprocessors.
