Install some period-correct software on it and have fun, it's kind of a neat looking machine and historically quite significant. As someone already mentioned it's not going to keep up with even very low end modern devices but that's not really the point of vintage computing. The thing that always strikes me is that for the most part old computers are every bit as powerful and useful as they ever were, it is only our expectations that have changed. I say "for the most part" because websites have also become tremendously bloated so with anything involving the internet YMMV. You can still use desktop productivity software, play music, edit photos, write code, play games, etc though.
