In 1984 Apple Computer unveiled their Macintosh. It included a new user interface that revolutionized the way people though about computer interaction. Originally referred to as simply 'Macintosh System', the underlying OS was a single-tasking disk system for the Motorola 68K CPU. Significant changes were made in MacOS 7.x.
Emulation note: For MacOS 0.x-6.x we recommend the vMac Mini emulator.
It is possible to write Macintosh 400k/800k images to a real disk using a Kryoflux.
Note: Wikipedia's/Apple's Developer CD Classic Mac OS 'System Software' numbering scheme is GARBAGE and should NOT be used.
