An article at Low End Mac from earlier this year, by Tyler Sable. It begins:
"System 7.5 and Mac OS 7.6 introduced many new features and greater modernity while staying within reach of most early Macintosh models.
I'm happy to report that System 7.5 and Mac OS 7.6 are the real deal. These versions of the Mac OS make connecting to and communicating with modern computers easy and convenient. They allow access to nearly every 68k-compatible application, and 7.5.3 and 7.5.5 are freely and legally available to boot!"

The fantastic 8-bit Apple II emulator for Mac OS X, Virtual ][ has been updated to version 5.5.

New in this release:
• The arrow keys on the keyboard can now be used as a joystick.
• The "enter" key on the numeric pad can now be used as an alternative "return" key. This is consistent with the numeric key pad of the Apple //e.
• Improved ProDOS compatibility of the Thunderclock emulation.
• Fixed a potential crash when the virtual machine is restarted.
• Fixed yet another issue with license key validation when Japanese is the system default language.
• Reorganized the long list of subjects in the documentation, in order to make it more accessible.

It begins:
"At the Worldwide Developer's Conference recently held in San Jose, Apple cut the ribbon on the major features of the next operating system for the Macintosh. Code-named Copland (but dubbed System 8 for this article), the new system promises dramatic changes to the Mac, from the desktop to the plumbing underneath."
