Delivering the keynote address at the Windows World annex to Comdex yesterday, Bill Gates announced that NT source code will be given to some US research institutions, including the Massachusetts Institute of Technology, the University of Washington, Stanford University, Browns University and Xerox Palo Alto Research Center and they will be free to make their own enhancements to the Microsoft Corp operating system: Unix System Laboratories Inc has been less encouraging of the university fraternity in recent years, and the move is intended to unsettle the Unix community; Gates also claimed NT’s Posix interface made it as easy to move applications here as to any of the versions of Unix out there.
