There were mixed feelings after the dissident Unix vendors – the Hamilton Group – met with AT&T late last week: some vendors were disturbed by Vittorio Cassoni’s opening remarks because he saw the System V and the Sun Microsystems SPARC architecture becoming the industry standard Unix environment – but others were encouraged by Cassoni’s pledge of more openness concerning Unix development and the fact that AT&T intends to deliver the next Unix release first on a 3B in 1989 – with source code for the 80386 and SPARC coming later – since some vendors had feared that it would be launched first on the SPARC, giving Sun an advantage: the vendors still feel that their fears have not yet been addressed but are unsure of their next move; AT&T will be addressing some of the points raised at a meeting scheduled for next week’s Uniforum.
