If you like playing old DOS games, you probably know that none of them will run on modern computers. But if you want to get rid of your old x286 machine, there is a solution called DOSBox that will make you very happy. DOSBox runs on Windows, Linux, and Mac machines and it acts as an x86 emulator with DOS so that you can run old DOS games on your modern computer. It's been tested as compatible with over 3000 DOS games, so the chances are pretty good that whatever game you like, or used to like, playing will run.
