The DOS version will run in DosBox or on actual hardware, and has EGA graphics (unless you run the 'terminal' version). The Linux version is console only and very bare-bones, although it can look a lot deeper if run on a modern machine! I do intend to make it compatible with the UCI protocol at some point.
