“You know, @hopesdead, has anyone told you you’re a real freakasaurus?”
In all seriousness, I always love a Star Trek episode/film involving a crew’s misadventures in the past (except the whole ENT space Nazi thing, which I have neither watched nor particularly want to watch).
In addition to the good suggestions for others in this thread (like setting it up as a portable gaming device or a server of sorts), it could also be set up as a low-distraction productivity machine. I don’t know how well something like LibreOffice would run on it, but I imagine you could probably use a simpler word processor or even a plain text editor.
Worst comes to worst, I wonder what hardware support for this thing is in something like ReactOS or FreeDOS.
