Someone has patched NCSA Mosaic to run on modern Linux systems (if that's not an oxymoron).I couldn't get it to build on OSX because of Motif (and port install openmotif didn't help). I dug in a bit but then the smell of gasoline and burning flesh drove me away.
It's not entirely clear to me why this "port" was necessary, since the last time I checked (which was five years ago) it was still possible to run the old NCSA and NSCP binaries on modern Linux systems just by installing the a.out kernel module and a couple other files.
