AT&T Announces Availability of Unix System V/386 Release 3.2

Morristown, N.J. -- August 22, 1988 -- PRN -- AT&T (NYSE: T) today said that its UNIX(R) System V/386 Release 3.2, which combines the features of AT&T's UNIX System V and the Microsoft Corporation's XENIX(R) operating system, is now generally available to the industry.

"The new release is a milestone for customers, because it lets them run both UNIX System V and XENIX applications on the same machine," said Michael DeFazio, director of system software at AT&T's Data Systems Group. "We think customers will make it the multitasking, multiuser operating system of choice for computers based on the INTEL 80386 microprocessor."

Release 3.2 is a key step for AT&T toward unifying the major derivatives of the UNIX operating system. The next step in AT&T's efforts to unify the major derivatives of the UNIX operating system will be delivery in mid-1989 of UNIX System V Release 4.0, which will merge the features of UNIX System V, XENIX, and Berkeley 4.2 derivatives into one product.

UNIX System V/386 Release 3.2 lets customers take full advantage of the 32-bit processing power of the INTEL 80386 microprocessor. It lets machines based on the INTEL 80386 microprocessor run all UNIX System V/386 or XENIX System V applications programs written for the INTEL 80286 or 80386 chips. When combined with commercially available companion products, such as Phoenix Technology's VP/ix(TM) or AT&T's Simul-Task product, UNIX System V/386 also can run thousands of PC applications now on the market.

AT&T also announced that for the first time the company will license use of the UNIX trademark to customers who distribute UNIX System V/386 Release 3.2.

UNIX System V/386 Release 3.2 makes full use of floating point chips, such as the INTEL 80287 and 80387 numeric coprocessors and the WEITEK 1167 floating point coprocessor, to speed up applications requiring mathematical calculations. Release 3.2 also incorporates state-of-the-art networking capabilities, including Streams and Remote File Sharing.

Release 3.2 is an AT&T product based on UNIX System V Release 3.0. The XENIX features were added by the Microsoft Corporation under contract to AT&T.
