Version 1.1 of NCSA Mosaic for the X Window System, a networked
information systems and World Wide Web browser, is now available:


NCSA Mosaic provides a consistent and easy-to-use hypermedia-based
interface into a wide variety of networked information sources,
including Gopher, WAIS, World Wide Web, NNTP/Usenet news, Techinfo,
FTP, local filesystems, Archie, finger, Hyper-G, HyTelnet, TeXinfo,
telnet, tn3270, and more.

This release of NCSA Mosaic is known to compile on the following

SGI (IRIX 4.0.2)
IBM (AIX 3.2)
Sun 4 (SunOS 4.1.2 with stock X11R4 and Motif 1.1).
DECstation 5000-200 (Ultrix).
DEC Alpha (OSF/1).

Rumor has it that Mosaic will compile on systems like:

Hewlett Packard HP/UX 7.x, 8.x, 9.x.
Dell SVR4
Sun Solaris 2.x
SCO Open Desktop
Harris Nighthawk
