NCD ANNOUNCES INDUSTRY'S EASIEST TO USE INTERNET ACCESS AND NAVIGATION
TOOL

Single Application and Familiar Windows File Manager User Interface
Provides One Interface To All Internet Resources

MOUNTAIN VIEW, Calif. -- March 13, 1995 -- Network Computing Devices, Inc.
(NASDAQ: NCDI) today announced Mariner, an easy-to-use Microsoft
Windows-based Internet tool which enables users to use one application to
access all information sources on the Internet. Unlike other Internet
products which package a group of applications, Mariner provides a unified
user interface to all Internet services and protocols, including World
Wide Web (WWW), Electronic Mail (send and receive), Net News, Internet
Relay Chat (IRC), File Transfer Protocol (FTP), Gopher, and Telnet. The
result is an exceptionally simple, powerful environment where users learn
one application, not many. This enables them to concentrate on using the
information and resources found on the Internet, rather than how to find
to those resources. NCD's Mariner is distinguished from all other Internet
offerings in that it is the first to use the familiar Windows File Manager
paradigm to offer superior file management and dynamic mapping
capabilities. It also supports off-line operation and optimizes
performance for dial-up and corporate LAN environments.

"The Internet is quickly becoming the standard way to communicate, present
information and conduct commerce electronically," said Mike Harrigan,
co-founder of NCD and NCD's vice president of Internet technologies. "Yet
it is our belief that in order to achieve mass acceptance, the user needs
to be shielded from the intricacies of the Internet. By unifying all of
the Internet applications, services and protocols into one package, and
incorporating our advanced navigation technology, Mariner makes it easy
for new users to quickly begin using the Internet while providing enormous
poiwer for experienced users."

EASIEST WAY TO MANAGE ALL INTERNET INFORMATION

Mariner is the only Internet client which uses a Windows File Manager-like
user interface to provide a consistent way to present, manage, structure
and record all Internet information. Using OLE 2.0 drag and drop
functionality, Mariner makes it easy for users to incorporate information
from anywhere on the Internet into their own personal subject folders or
other applications. For example, a user can develop a "sports folder"
which includes E-mail messages from friends, stats from the WWW, analysis
from Newgroups, and historical records from Gopher sites all in one
folder. In addition, NCD's unique navigation tool dynamically creates a
map of the users' travels through the Internet, then stores that
information on a local disk drive. The user can go back later and in a
single click, re-trace his steps and get updated information. No other
application provides the ability to incorporate all types of Internet
information into a single subject folder and provides this dynamic mapping
capability. These capabilities are so unique that NCD has filed for a
patent on this technology.

FIRST INTERNET CLIENT TO OPERATE "OFF-LINE"

Mariner is also the only integrated Internet client that can operate
"off-line". Its persistent cache technology records items on a local disk
so E-mail messages, documents, Newsgroups and other information sources
can be viewed and worked on off-line -- eliminating the need to be
"plugged in" continually. This same technology enables practically instant
response when subsequent requests are made for information. When Mariner
is back "on-line", it can check the dates of the marked documents and
update them with the most recent versions available.

DESIGNED FOR HIGH PERFORMANCE

NCD's Mariner is built around a multi-tasking architecture which allows
many activities to be performed simultaneously. Thus users can record and
explore multiple web sites, send and receive E-mail, and read Net News,
all at the same time. Mariner also supports dynamic rendering of images,
which means the user can be reading the HMTL text and navigating to other
hyperlinked documents, while the images are being retrieved. The Windows
File Manager paradigm and persistent caching capabilities dramatically
speed up navigation in dial-up and corporate LAN environments. The
combination of these capabilities makes Mariner one of the fastest
products on the market

TCP/IP STACK INCORPORATED IN UNIFIED PACKAGE

Mariner includes everything needed to begin using the Internet in one
comprehensive package, including a complete Winsock VxD TCP/IP protocol
stack with PPP, SLIP, CSLIP, and Ethernet drivers; support for all
Internet services and protocols; and support for common in-line image
formats such as GIF 89A, JPEG, BMP, and XBM.

Future Directions

SECURITY

As charter members of the World Wide Web Consortium (W3C) and CommerceNet,
future versions NCD's Mariner will support the Secure Hyper Text Transport
Protocol (SHTTP). However, Mariner is not limited to the SHTTP protocol.
Mariner will provide an Open Secure Transaction Architecture that will
simultaneously support multiple security implementations and standards.

USING MARINER TO BUILD NEW CLASS OF INTERNET-ENABLED APPLICATIONS

One of the most exciting aspects of NCD's new product is that it provides a
platform for building a new class of Internet-enabled applications.
Instead of using proprietary services, protocols and networks, these new
applications will use the standard protocols and services of the Internet
to solve both corporate and consumer networking issues using a client/
server model.

"We believe that in the very near future application developers will want
to combine the information and computing power available on a local PC
with the information and computing power of remote servers via the
Internet," said Harrigan. "These Internet-enabled applications will do
everything from dynamically updating stock portfolios to providing
information for CD- based multimedia games. By combining all the required
Internet services and protocols into one highly unified package, and
providing an object-oriented architecture, Mariner is uniquely suited to
facilitate the development of these new applications."

In the future, NCD will significantly simplify the development of these
applications by delivering an Internet-enabled toolkit which developers
can use to build their applications. This toolkit will include APIs for
access to NCD's Internet services and applications, as well as access to
the other unique capabilities, such as persistent cache and off-line
operation.
