Heh, I just remembered that I have a drawer of old devices; found my old Palm Pilot M105. It uses AAA batteries so I popped 2 in and it boots just fine. Now I need to enable the serial port on my PC so that I can transfer files to it. Is this a reasonable reader for it or is there something better?

And this for connecting the Palm to my pc.

Edit: Even better, I found a Palm III xe. And the cradle I found is for it, not the M105.
And a Dell Windows Mobile PDA (not Windows CE). Now to see if its battery holds a charge ...
I feel like a necromancer, waking up these dead devices. "Skeleton CSS" indeed.
