ENHANCED PC X SERVER FROM NCD IS FIRST WITH AUDIO SUPPORT, WINDOWS 'FOLDER
TABS'

MOUNTAIN VIEW, Calif., July 25, 1994 -- The first PC-to-UNIX connectivity
software that offers audio support and uses the advanced Microsoft Windows
"Folder Tabs" user interface technology has been introduced by Network
Computing Devices.

PC-Xware 2.0, NCD's third-generation PC X server, is a significantly
enhanced version of the Windows software NCD has been shipping since
mid-1993 to give personal computer NCD users access to applications
running on UNIX hosts. In addition to sound support and a new user
interface that completely masks the complexity of accessing LAN-attached
UNIX systems, the new version offers an integral NCD-developed TCP/IP
stack based on 32-bit VxD technology, dramatic performance improvements,
simpler installation and a new option package with NCD's Z-Mail
electronic-messaging software.

Tracking Windows User Interface Technology

NCD President Judy Estrin said, "PC-to-UNIX integration tools, or PC X
servers, typically have lagged behind other PC applications in providing
simple, intuitive user interfaces. PC-Xware 2.0 is the first such product
to track the latest PC user interface development, offering the newest
technology at the same time Microsoft is delivering it for Windows. It
also adds multimedia support -- both sound and imaging -- putting PC X
servers on a virtually equal footing with workstations and X terminals
that offer these features."

PC-Xware 2.0, derived from the 32-bit NCDware multitasking X server
software shipped on more than 200,000 NCD X terminals in the past six
years, incorporates two multimedia software capabilities. The Network
Audio System (now in the public domain) permits CD-quality playing of the
audio portions of UNIX applications -- a first for PC X servers -- using
such products as Creative Labs' SoundBlaster card. The Simple Imaging
Extension enables the PC to display scanned black-and-white images, such
as faxes, insurance forms or X-rays, from UNIX applications. Compatible
with UNIX-based applications from a variety of imaging vendors, SE lets
the user locally zoom, scale, pan and rotate images.

"Until now PC users couldn't bring the sound portions of UNIX applications
to their desktop PCs," Estrin said. "Voice-annotated electronic mail would
come without the voice, training applications without the accompanying
oral instruction. PC-Xware users now can take full advantage of such
applications as Mosaic, which combine graphics, sound and images."

PC-Xware 2.0 utilizes the innovative new Microsoft user interface approach
called Folder Tabs, in use in new applications such as Microsoft Office.
The use of Folder Tabs makes all choices visible on screen, eliminating
the need to click through various pull-down menus and dialog boxes in
search of information; all applications appear in one folder,
configuration options in another, the user database in still another. By
facilitating quick access to the server's large feature set, this greatly
speeds such tasks as configuring interfaces, creating icons and launching
applications.

Fully Integrated 32-Bit TCP/IP VxD Stack

New NCD-developed TCP/IP local networking software based on the latest
32-bit Windows VxD technology is fully integrated into PC-Xware 2.0,
eliminating the separate installation process associated with the earlier
version's bundled third-party stack -- a 16-bit DLL (Dynamic Link Library)
offering from NetManage, Inc. Implemented at the kernel level of Windows,
VxD offers better performance than traditional TCP/IP products and
consumes virtually no low system memory. For the user who favors another
TCP/IP stack, however, PC-Xware 2.0 continues to support NetManage's Newt
and some 14 other third-party products directly, and many more through the
WinSock API.

For extended TCP/IP capability, PC-Xware 2.0 continues to offer its NetPack
option for FTP file transfer, TN3270 terminal emulation and miscellaneous
TCP/IP utilities; a NetPack NFS option also adds NFS client and server
functions. Also available is a new electronic-mail option, NetPack Mail,
which adds NCD's Z-Mail for Windows to any PC-Xware version.

For remote serial connectivity, PC-Xware 2.0 incorporates the latest
version of XRemote, the NCD-developed data-compression algorithm which is
the basis for low-bandwidth X (LBX), the X Consortium's standard for
remote X operation. With high-speed modems, XRemote can transfer data at
rates up to 57.6 kilobits per second.

PC-Xware 2.0 performance has been increased approximately 20 percent over
the previous version. On 80486-based PCs, PC-Xware 2.0 delivers an Xmark
rating greater than 1.0, and an Xstone rating of up to 150,000.

Enhanced VT320 terminal emulation allows PC-Xware 2.0 parameters to be
configured both locally and remotely. Users can access character-based
terminal applications via the same simple point-and-click process as other
applications, and can cut and paste between Telnet and Windows sessions.

Installation Software Automatically Surveys PC Resources

Installation of PC-Xware 2.0 has been dramatically improved and shortened.
The software starts out by "surveying" the PC to see that available
resources -- memory, network interfaces, etc. -- can support the
applications and options the user has chosen. Based on this survey,
PC-Xware makes suggestions about the configuration that can resolve
problems and increase performance (e.g., add more memory to improve
performance or increase Windows swap space).

Several other new features boost the convenience and productivity of
PC-Xware use. A Local Print Daemon allows UNIX applications to print on
the same PC printer used for Windows applications, eliminating the need
for duplicate printers. An icon is automatically created the first time a
user connects to a UNIX application, making future connection a simple
matter of point and-click, just as with Excel or Word. Automatic font
selection ensures that, if an application requests an unavailable font, a
font with similar characteristics will be supplied. And support for Rlogin
lets the user log in remotely to a UNIX host.

Like the earlier version, PC-Xware 2.0 provides the remote configuration
and diagnostics essential to large network environments. All networked PCs
can be centrally loaded or updated from one copy of PC-Xware on the file
server, ensuring consistency among software versions. PC-Xware options can
be modified from any X terminal, PC or workstation on the network. And
PC-Xware network activity can be centrally monitored using the Simple
Network Management Protocol (SNMP) with X-specific MIB extensions.

Pricing and Availability

Available in August, PC-Xware 2.0 is priced at $545 (the same price as
PC-Xware 1.0). PC-Xware with NetPack is $735 and with NetPack NFS is $795.
The NetPack Mail option is priced at $150 when purchased with any version
of PC-Xware. Current users of PC-Xware 1.0 can upgrade to the new version
for $125.

Network Computing Devices, Inc., formed in February 1988, provides
information-access solutions for client-server computing environments. NCD
is the leading worldwide supplier of X Window System terminals, with a
broad family of color and monochrome units, and makes PC-X server software
