As for pc architecture, I've got a PII 200 that still works. Of course I have the gratuitous Commadore 64 sitting in my room, but I haven't fired it up in years. I threw out an old Intellivision a few years ago, when we cleaned out a ton of stuff that never got unpacked after we moved here back in '95. I don't know if it still worked after sitting in a damp basement for 7 or so years, but it was working when I packed it. Makes me kinda sad.
