Power Mac
Power Macintosh

    Apple Computer's personal computer based on the
   PowerPC, introduced on 1994-03-14.

   The Power Mac G4 (Quicksilver 2002) was the first Power Mac to
   clock at 1 GHz.  In mid-2003, the Power Mac G5 was released,
   the first Mac to be based on a 64-bit architecture.  IBM
   manufactured the CPU for this new model.  The clock speed was
   initially 1.6 GHz but a dual 2 GHz system was available in
   September.  Existing 680x0 code (both applications and
   device drivers) run on Power Mac 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 Mac runs Macintosh operating system from System
   7.5 to Mac OS 8.5.
