Welcome to MindTerm on
If you'd like a secure shell but do not have an SSH client on the computer you're using, you can just load up the MindTerm applet in any Java-enabled web browser.
Click here for for a version that runs within the browser's window and here for a version that spawns a new window. The separate window version also gives you a menu bar for adjusting fonts, colors, size, etc.
Netscape on Macintosh does not ship with a complete Java Runtime Environment. To get MindTerm to work on a Mac you'll either have to use Internet Explorer, or you'll have to install both Apple's MacOS Runtime for Java (MRJ) from Apple's Java page, and Netscape's MRJ plugin for Macintosh from mozilla.org, and then use this special Macintosh version of the page that starts the MindTerm applet.
