Following AT&T’s decision to standardise on Sun Microsystems’ SPARC Scalable Processor ARChitecture, companies are rushing to follow suit, and the latest to take the plung is Xerox Corp. Xerox has decided to make its document processing products compatible with the SPARC and the planned unified Unix, and Sun plans to enhance its SunOs Sun Operating System implementat-ion of combined Berkeley and System V Unix to enable support of Xerox Network Systems standards, applications and multinational products. Xerox and Sun are al-so negotiating agreements under which Xerox will buy and/or manufacture Sun components, workstation, and server products for itself and for affiliates Rank Xerox Ltd, Fuji Xerox Co Ltd and Xerox Canada Inc. Xerox also will work with Sun to migrate its ViewPoint applications software and Network Services environment to the SPARC architecture. Over the next five years, Xerox now plans to use the SPARC architecture throughout its document processing products and systems.
