It's older than USB connectors, so its only "standard" connection method is an external floppy drive on a custom connector that nothing uses anymore.
But it does have a PCMCIA slot on it, and that you can use for one of those PCMCIA to digital camera storage card converters if you have something else that can also talk to the digital camera storage card. (My digital camera takes CF cards, so I've got a PCMCIA to CF adaptor that can go into the old notebook and then the CF card gets read on my digicam card reader that connects via a USB port. Yeah, it's pretty darn convoluted... but it would theoretically give you both more file storage and a way to get things back and forth that wouldn't be a floppy.)
Here's some links to the kinds of critters I'm talking about:
64 MB CF Card (I know this will work because I have one this size in my camera that I've used with a PCMCIA adapter, and it's basically 64 floppies on one bitty thing... but the several-gig cards would give you basically the entire size of the critter's hard drive in the same amount of space if Windows 95 is capable of recognizing them, which I haven't actually tested out due to not owning anything higher than 256 mb for my camera.)
Anyway, possible food for thought? If you guys are interested, I'll try to get the old box booted up and cleaned up this weekend. I'm also not sure how good its battery is anymore, but its power adapter has always worked fine if you're thinking libraries or places reasonably close to power (or even sitting by the TV typing and watching, which is also fun. :D)
