Power Macintosh

(computer)

Power Macintosh - Apple Computer's personal computer based on the PowerPC, introduced on 1994-03-14. Existing 680x0 code (both applications and device drivers) run on Power Macintosh systems without modification via a Motorola 68LC040 emulator. The performance of these unmodified applications is equivalent to a fast 68040-based Macintosh, e.g. a fast Macintosh Quadra. The Power Macintosh runs Macintosh operating system from System 7.5 to Mac OS 8.5. http://www.info.apple.com/ppc/ppchome.html.
