There are old home security camera systems that run the camera interface on this thing, but you would have to reinstall the Windows OS on it and I doubt you have the software.
You can get old Linux versions for free, but you would first need to get on a pc that works with an internet connection, download it on that, then assuming your junker has a CD reader, then install it. But you would probably need to buy a new h/d but why dump money into this thing?
You can buy a new desktop pc/tower for under $500 these days (but not so for laptop), but I assume you already have other computers/pcs/laptops. A lot of "storage units" businesses take old computers for recycling (or something - do they melt them down? Not sure what the hell they do with them, but I turn in my old junkers to them)...
