MOUNTAIN VIEW, Calif. --April 24, 1990-- Sun Microsystems has announced
that X/Open is specifying part of Sun's Network File System (NFS) as
one of two protocols for connecting personal computers to UNIX(R)-based
systems.  X/Open will publish these specifications in a future issue of
the X/Open Portability Guide (XPG).

NFS, a de facto standard for file sharing in mixed-vendor computer
networks, is available from several vendors of PC-DOS equipment.  Sun
itself has shipped more than 200,000 copies of its PC-NFS networking
software.  PC-NFS allows PCs to access files and resources such as
printers throughout a heterogeneous network.

X/Open has specified the PC portion of the NFS protocol as one of two
protocols for connecting personal computers to UNIX-based systems.  In
addition to PC-NFS's protocol, X/Open will also specify Microsoft's SMB
protocol for XPG-compliant PC connectivity.

Sun's Open Network Computing (ONC)/NFS platform for distributed
computing has been licensed to more than 290 organizations worldwide
and has been implemented on all major operating systems, including
UNIX, MVS, VM, VMS and PC-DOS.  The estimated installed based of
systems supporting ONC/NFS exceeds one million.

"We welcome X/Open's selection of NFS for PC interworking," said Eric
Schmidt, vice president of Sun's General System Group. "This is further
recognition that Sun's ONC/NFS technology is the leader for distributed
computing.  It is a standard part of AT&T's UNIX System V Release 4 and
we hope it will be selected by the Open Software Foundation as their
distributed computing choice."

Sun is actively participating in X/Open's continuing work on general
file sharing protocols.

X/Open is an independent, non-profit consortium of international
computer system vendors that is developing the Common Applications
Environment, specified in the X/Open Portability Guide.  The XPG
defines standard interfaces between systems and applications software.
Sun has been a member of X/Open since January 1988 and is currently
shipping XPG2-branded software in its SunOS(TM) 4.1 release.  Sun and
AT&T co-developed UNIX System V Release 4, which has been acknowledged
by X/Open as the first shipped product to be compliant with XPG3.

Sun Microsystems, Inc., headquartered in Mountain View, Calif., is the
leading worldwide supplier of network-based distributed computing
systems, including professional workstations, servers and UNIX
operating system and productivity software.
