System Software (0-6) System 6.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 |

Release notes
System 6.0 finally brings the version numbers mostly in sync. Adds improvements to the MultiFinder and LaserWriter drivers, and support for the 800k/1.44mb SuperDrive.
System 6.0.3 is considered the first stable version of System 6.
System 6.0.6 was not officially released due to a bug. However, some Macintosh Classics mistakenly shipped with a copy. It contains a bug that makes the Mac crash when connected to an AppleTalk network. This version should not be used.
System 6.0.8L was a limited maintenance release to support the Asia Pacific market. It was needed in some countries where System 7 localization had been delayed. It enabled System 6 to run on the Macintosh Classic, Classic II, PowerBook 100, Macintosh LC and Macintosh LC II with high-bit language support and up to date printer support. It had no user interface changes. It will not run on other Macintosh models.
Note: 1.44mb floppy disk images may be written from a PC with WinImage, even with a USB floppy drive.
