I might have figured out what to do with some of the old hardware I have kicking around. It involves 2-Disk Xwindow embedded Linux:
2-Disk X window embedded Linux is a tiny net-centric Linux that aims at portable secure remote system usage. It contains many utilities including: X Windows, vncviewer, rdesktop, a Web browser, a file manager, a text editor, a terminal, a window manager, a menu system, a dialog system, X scripting facilities, and many others. It aims to work from 1 or 2 floppy disks in any remote location.
Note to open source developers: take advantage of hosting provided by Sourceforge or others. Swatting popups when looking at free software isn’t too much fun.
