There are instructions around somewhere on the board to get the "ae" going (sort-of-ish emacs like). I'll recap here.
The ae binary is attached to this post (place into suitable bin directory and chmod 755 or so), and the /etc/ae.rc file is attached to this one (Goes into /etc as the name says). The link to the libslang library I had in this post doesn't work (Frank's web site seems to have gone missing), but I've attached it to this post (zip'ed).
Just put it in /lib . But since ae looks for libslang.so.1 and you got the ..so.1.3.9 file, you need to either rename it or create a symlink in /lib, like this:
ln -s /lib/libslang.so.1.3.9 /lib/libslang.so.1

Yes, you can download - edit - reupload the file, as long as you use an editor that is capable of saving in Unix format (ie linefeed as line separator, in Windows for instance Ultra Edit)
