W00t! Sources: Apple to Use IBM Processor SAN JOSE, Calif., Oct 14, 2002 (AP Online via COMTEX) -- Apple Computer Inc., which for months has been encouraging PC users to switch to its Macintosh computers, is on the verge of some switching itself. The company, which has used Motorola microprocessors in most of its Macs since 1984, is the customer of a line of next-generation processors to be unveiled Monday by International Business Machines Corp., according to industry sources. Unlike today's Windows and Mac desktops, the IBM PowerPC 970 can process data in 64-bit chunks as well as today's standard 32-bit chunks. Sixty-four bit chips, which can address massive amounts of memory, are mostly found today in powerful servers.
