NCSA Mosaic on the Mac

A nostalgia article on PC World, Finding Stuff Online: 20 Years of Innovative Search Engines, reminded me that I should share my running version of NCSA Mosaic v2.7 with others. I don’t know where I got it, but it might have been from the Floodgap guys.

To that end, here is my compiled version of NCSA Mosaic, running on Mac OS X 10.6 Snow Leopard. You’ll need to download OpenMotif. The 10.5 version worked for me (backup hosted here).

When you run it, and you have OpenMotif installed, X11.app should start up, and you should see good ol’ NCSA Mosaic v2.7. Since it runs in XWindows, you can run it remotely over an SSH tunnel too. Enjoy!

    Silly of me, but I’m trying to get a compiled version of Mosaic 2.7 (haven’t the foggiest idea how to use a compiler after 30 years on the Mac).

    Your link to the version you built is broken on:

    The link:

    fails with an SSL error and plain HTTP gives a ‘not found’.

    Thank you for your efforts.

      Thanks for the heads up. I need to find my own binary and move it AWS or something. -Rob

    I would also love to take a look at this! Maybe it’s something that can be put on github instead?
