System Software (0-6) System 4.x
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.
The Macintosh originally came bundled with a Guided Tour of Macintosh, MacWrite, MacPaint, and a Tour of MacPaint and MacWrite.
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.
