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.

Other Mac OS Versions:
| 1.x-6.x | 7.x | 8.x | 9.x | MacOS X | All |
