Users of 80486-based personal computers may be able to run Macintosh System 7.1 on their machines if a project under way at Apple Computer Inc comes to fruition. According to MacWeek magazine, Apple has a project under way under the code name Star Trek which involves a rewrite of System 7.1 to provide users of machines built around the 80486 and above an alternative to Microsoft Corp’s Windows. It sounds as if the project has the active backing of Novell Inc, because it is said that the software is being built atop a future release of the DR DOS MS-DOS-compatible operating system.Apple is said not to have made a final commitment to release the software, and the big question is where Apple sees the base of applications for it, but word is that if the go-ahead is given, the product could come to market before the end of the year.
