Download DosBox and find a site that distributes abandonware (which i in no way recommend downloading due to possible copyright infringement.) There are some great DOS games out there and you'll probably be able to find them by yourself, but my favorites include Shadowrun (RPG-ish game), Alter Ego (Text-based life sim), and DOOM.
