AT&T Ships Early Version Of Unix System V Release 4.0 Source Code

MORRISTOWN, N.J., March 31, 1989 -- PRNewswire -- AT&T (NYSE: T) today shipped an early version of UNIX(R) System V Release 4.0 source code to members of UNIX International, Inc., fulfilling the company's commitment to give the industry access to an early version of the new operating system through UNIX International.

"We met our commitment and we're proud of that," said Larry Dooling, president of AT&T's UNIX software operation. "UNIX System V Release 4.0 is real. So are AT&T's commitments to UNIX International, to the open systems industry, and to UNIX System customers."

All principal and general members of UNIX International, Inc., were given an opportunity to receive the early version of the source code on a non-disclosure basis. The code was shipped worldwide to members who asked to receive it. AT&T also provided UNIX International members preliminary license terms and conditions for UNIX System V Release 4.0.

Peter Cunningham, president of UNIX International, said, "With the release of this early version of UNIX System V Release 4.0, AT&T has met its first commitment to us and to the industry. We're confident AT&T will continue to work with us to make sure customers and systems vendors gain the full benefits of a smooth migration into the future with UNIX System V."

Copies of the early source code were shipped by AT&T's UNIX software operation in Greensboro, N.C., and by AT&T's UNIX Europe and UNIX Pacific offices in London and Tokyo to ensure simultaneous delivery to participating computer vendors.

Vendors who get the early source code may begin developing their own operating system offerings based on Release 4.0, AT&T said.

The UNIX System V Release 4.0 operating system, scheduled for general availability this fall, unifies the features of UNIX System V, Microsoft's XENIX(R), Sun Microsystem's SunOS(TM), and the Berkeley 4.2 versions of the UNIX System in one release. This will bring a vastly expanded range of applications to UNIX System customers and expanded market opportunities to software developers.
