Power Macintosh





Power Macintosh, or Power Mac, is the name of a line of Apple Macintosh
personal computer based on a PowerPC processor. Apple Computer started
producing Power Macs in 1994; earlier models were based on Motorola 68000
processors, and the MacOS operating system released with the new machines
included an emulator to enable programs written for the older machines to
run without changes.

Other PowerPC-based Macintosh lines include the iMac, iBook, and various
PowerBook models since 1995.

The earliest Power Macs were PowerPC 60x processor-based, followed by the
G3, the G4, and recently the G5. Many have dual processor configurations.
