Apple's Call for Unity -- Apple has finally released the long-awaited retail version of System 7.5.3. This version can install a universal system that will boot anything from a Mac Plus onwards. Codenamed Unity, the retail version of System 7.5.3 includes the fixes from System 7.5.3 Revision 2 (see TidBITS-332), LaserWriter 8.3.4 (see TidBITS-333), support for 8x CD-ROM drives, the Apple Internet Connection Kit, and an optional installer for OpenDoc 1.0.4. The software costs $99 and should be available shortly through the usual retail software channels on floppy disk or CD-ROM; current System 7.5 owners can upgrade for $49 by calling 800/293-6617, ext. 1 with proof of ownership. For many Mac users and support personnel, installing System 7.5.3 required running through an involved series of installers, downloads, and patches - it's nice that Apple finally put everything together in a single release, even if it will soon be eclipsed by new versions of Open Transport and other system components. Apple says international versions of Unity should be available in the next 90 days. [GD]
