		First Networking Product to Support

	Enhanced Version of PC-NFS Programmer's Toolkit Released

BILLERICA, Mass. -- April 13, 1992 -- SunSelect(TM), a Sun
Microsystems, Inc.  business, today introduced version 4.0 of its
popular PC-NFS(R) software and a new enhanced version of the PC-NFS
Programmer's Toolkit, the companion developer's product for writing
client-server PC-NFS applications.

PC-NFS software integrates personal computers into open, UNIX(R) -based
client-server environments, allowing personal computer users to access
files and resources on all workstations and servers, minicomputers,
mainframes or other systems that support ONC(TM)/NFS(R). Users operate
within their familiar MS-DOS(R) and MS-Windows(R) environments, but
have access to distributed network resources such as powerful
fileservers, high-performance printers and worldwide electronic mail
systems through the use of open standards such as TCP/IP and NFS. In
effect, PC-NFS software lets personal computers become full
participants in local- and wide-area networks, providing a platform for
running distributed, client-server applications.

PC-NFS software was the first product on the market to integrate UNIX
resources with the MS-DOS platform. Previous versions of the PC-NFS
product are now installed in more than 700,000 personal computers
worldwide.

What's New In Version 4.0

The new version of PC-NFS software is the first to support
MS-Windows 3.1 as well as MS-DOS 5.0. Using standard MS-Windows
pull-down menus, PC-NFS 4.0 software users can connect to and browse
remote and local network resources such as printers, servers and
filesystems. Users can run multiple MS-Windows, MS-DOS and PC-NFS
applications simultaneously. The new version also includes a built-in
console messaging application that allows MS-Windows, MS-DOS and UNIX
users and administrators to communicate quickly and easily across the
network.

Through enhanced Network Driver Interface Specification (NDIS) support,
the PC-NFS 4.0 product now provides 4-Mbps and switchable 4/16-Mbps
Token Ring drivers for integration into Token Ring environments, and
continues to support Ethernet networks as well. PC-NFS users can access
more than one server operating system, such as Novell's NetWare(R) and
Banyan VINES(TM), simultaneously. Installation of the NDIS facilities
is now automated.

PC-NFS 4.0 software includes new ease-of-use features for both users
and system administrators. Extensive on-line help is available for
PC-NFS software under MS-Windows; PC-NFS utilities are available
through MS-Windows icons; and installation of primary functions,
upgrades and the NDIS drivers has been simplified. For system
administrators, server-based upgrades are offered, and enhanced SNMP
MIB-II provides improved integration with the SunNet(TM) Manager
network management platform and other network management hosts. The new
version of PC-NFS software also enhances the PC print server capability
by offering a dedicated mode option in addition to the proven
background mode. Performance and functionality is improved in both
modes.

"We found the MS-Windows support very impressive, especially the new
console messaging feature, which will allow our system managers to warn
users of potential problems or service notifications," said Jean-Pascal
Lange, systems administrator for Eurostat, the statistical bureau of
the European Community (EC).

Additional PC-NFS Products

PC-NFS 4.0 software is the cornerstone of the PC-NFS product family.
Three additional PC-NFS products are also marketed by SunSelect.

	PC-NFS LifeLine(TM) Mail and Backup delivers fully-integrated
electronic mail and enables users to backup files across heterogeneous
networks.

	PC-NFS Advanced Telnet extends the telnet terminal emulation
capabilities of PC-NFS software, enabling PCs to take advantage of
powerful environments by emulating a variety of popular mainframe and
other host terminals.

	PC-NFS Programmer's Toolkit provides development tools and
industry-standard protocols to create client-server applications in
which various parts of the applications are performed by different
systems on the network.

PC-NFS Programmer's Toolkit 4.0

The new release of the PC-NFS Programmer's Toolkit, Version 4.0, is the
first to enable developers to write TCP/IP network-based distributed
MS-Windows applications in addition to MS-DOS applications. The
enhanced product is also the first to join industry standard APIs (XTI
and TIRPC) with TCP/IP on the MS-DOS 5.0/MS-Windows 3.1 platform.

To facilitate fast and easy programming, the Toolkit now supports the
industry's most commonly used compiler products:  the Microsoft C 6.0
compiler and the Turbo C++ 2.0 and 3.0 compilers from Borland. The
PC-NFS Programmer's Toolkit also provides all transport-independent and
transport-specific RPC client calls (TIRPC); X/Open Transport Interface
Routines (XTI); XDR, Sun's standard for data interchange between
dissimilar machines; the NIS network naming service; and BSD sockets.

The Toolkit has been used to create a wide variety of software
products, including X Window System applications, terminal emulators,
and database, CAD/CAM and document control packages.  In fact, the
Toolkit was used to develop PC-NFS Advanced Telnet and PC-NFS LifeLine
Mail and Backup.
