7 AristotlePagaltzis 5 [MacOS] Classic shares many overall design choices with the later MicrosoftWindows (prior to Win32.) It used CooperativeMultitasking and lacked ProtectedMemory, so any application could crash or freeze the entire system. It was initially written for the [Motorola] [680x0] [CPU] architecture, but System 7.5 was hacked to run on [PowerPC]. System 8 was supposed to be a full [PowerPC] rewrite, but the rewrite effort codenamed [Copland] was so late that eventually [Apple] cancelled it and bought [NeXT] instead. The [NeXT] engineers effectively rewrote NeXTStep, incorporating a few features from [Copland] (such as [Carbon]), and created [MacOSX]. It took so long that AppleCorporation might as well have just finished [Copland]. System 8.5 through 9 sport the familiar LookAndFeel.
