Thank you for your interest in the MS Windows version of NCSA Mosaic.

NCSA Mosaic is a network navigational tool that allows the user access 
to networked information with the click of a button.  The Internet is 
the primary source of this world wide information.  With more and more 
people using the Internet the amount of information available is 
literally exploding.  NCSA Mosaic was designed to provide the user 
transparent and seamless access to nearly all of these information 
sources and services.  NCSA Mosaic gives the user a mechanism that will
retrieve and display a wide variety of data types.  These data types 
typically include text, image, movie and audio files.  There are now
two flavors of Mosaic.  One for IBM compatable PCs running Windows 3.1, 
Windows for Workgroups or Windows NT and the other is for the DEC alpha 
running Windows NT.   The current versions are:
	IBM compatable PCs  =  wmos20a5.zip 
	DEC alpha           =  DMOS2A5.zip


*** Required Environment ***

In order to use Mosaic you must have direct access to the network.
ie.  Either your machine has a network card and it's connected to the 
network or you use your modem to call a terminal server that allows
SLIP or PPP connections.  This direct access must support the WinSock
networking specification.  To run Mosaic for Microsoft Windows, you will 
need a system running Microsoft Windows 3.1 in enhanced mode, a 1.1 
compliant winsock.dll and Microsofts win32s software. Windows NT users
have these .dlls built in.

Mosaic requires an absolute minimum of an 80386SX-based machine with 4M
RAM. Our recommended configuration is a 33-MHz, or faster, 80486 with 
at least 8 meg of RAM.


*** Required Software ***
Windows 3.1 and Windows for Workgroups

A winsock.dll.  The winsock.dll provides the TCP/IP networking 
under windows.  NCSA Mosaic for MS Windows is a winsock1.1 compliant 
program.   If you are using a commercial TCP/IP stack such as PC-NFS 
or running a local area network such as Novell in addition to TCP/IP,
you need to contact your network vendor directly about obtaining the 
Winsock DLL.  If you are accessing the Internet with a stand-alone PC
running Windows, you may use a shareware winsock called the "Trumpet
Software International Winsock".  We have a copy of the Trumpet software
in the PC/Mosaic/sockets directory of our ftp server, ftp.ncsa.uiuc.edu.
The official copy can be found  at ftp.utas.edu.au in the
pc/trumpet/winsock directory.


Microsofts Win32s software

Version 2.0alpha5 is a 32-bit application and it requires the win32s
software.  Win32s allows you to run 32-bit Windows applications which do
not use Windows  "NT-specific features" under Windows 3.1 and Windows for
Workgroups.  Win32s was developed by Microsoft and it is freely distributed
to licensed users of Windows 3.1 or Windows for Workgroups.  If you
already use other 32-bit Windows applications then you should already have
this software installed in your /windows/system/win32s directory.  If Mosaic
is your first 32-bit application then you will need to obtain the win32s.zip
file from our ftp server.  You can get to this file via Mosaic by clicking on
the "Obtaining a new version of Mosaic for MS Windows" link on our home page
and following the link to win32s.  You can also find it in the /PC/Mosaic 
directory of our anonymous ftp server.


The World Wide Web
------------------

For more information about NCSA Mosaic and the World Wide Web, we recommend
you take a look at the /Mosaic/mosaic-papers directory on our ftp server.
The file mosaic.ps.Z gives a technical overview of the X windows version
of NSCA Mosaic.  The MS Windows and Macintosh versions will support the
same basic functionality as is described.
