for Macintosh, and at http://www.ncsa.uiuc.edu/SDG/Software/WinMosaic/HomePage.html
for Windows. Both source code and binaries for a range of Unix workstations, Macintosh and PC/DOS are available. (On a Unix platform you do not have to have Motif installed on your system to run Mosaic IF you pick up a precompiled binary. You do, however, need Motif 1.1 to compile Mosaic.)

Before you start Netscape or Mosaic, make sure xv, ghostview, and other auxiliary programs are installed on your system. The easiest way to check is with the which command:
% which xv xv is /local/apps/X11/bin/xvIf xv is not installed (or not in your path) which will print something like ``xv not found.'' The other programs these browsers use to display images are ghostview (to display Postscript files), xdvi (for LaTeX output), and
mpeg_playfor MPEG format movies. To see the complete list of these external programs, refer to the mosaic on-line documentation under the subject of ``X resources.''
