Apple Computer Inc added four new Power Macintoshes yesterday, improving performance by as much as 50%, and offered two iAPX-86 options on one of them. The new line includes the Power Macintosh 9500/150, 8500/150 and 8500/132, 7600/120 and 7200/120. The 7200/120 PC Compatible comes with either a 100MHz Pentium board or an entry-level 100MHz 586 board – but Apple does not say which chip is used, although it sounds like Advanced Micro Devices Inc’s 100MHz Am486. Both Peripheral Component Interconnect boards are available separately. Users can run Mac OS and MS-DOS or Windows software concurrently, switching between the environments without rebooting, copy and paste data between the Mac OS and Windows, and access Windows files and folders from Mac OS and vice versa, and can access Macintosh-compatible printers and modems from the MS-DOS and Windows environments. The 7 entry-level board comes with 128Kb secondary cache and 8Mb to 64Mb memory and is claimed to match a 75MHz Pentium. The 12 100MHz Pentium board has 256Kb secondary cache and 8Mb to 72Mb memory; the PowerPC 604 in the 7200/120 PC Compatible also has 8Mb memory. Both boards incorporate an ATI Mach64 video controller, from ATI Technologies Inc of Toronto, for accelerated Super VGA compatibility up to 24-bits per pixel. Out in June, it is $2,600 with 1.2Gb disk, $2,800 for the 100MHz Pentium version. Bought separately, the boards are $800 and $1,050. For all the new Power Macs, Apple has raised the minimum hard disk drive configuration to 1.2Gb. The 7200 with 120MHz 604 and 8Mb is $1,900; biggest of the new boxes, the 150MHz 9500/150 costs $4,700 with 16Mb and 2Gb disk.
