Thanks to Wengier’s heroic work, DOSBox-X is now the only DOS emulator fully suitable for the Mac. I’ve put together an AppleScript wrapper around it, which makes possible printing and PDF-creation. It’s a work in progress, but worth trying. It comes with absolutely no support, but it should be fairly easy to sort it out: http://www.columbia.edu/~em36/DOSBox-X-App.zip
