JsDOSBox is a JavaScript port of jDosbox. It is capable of running dos programs from the early 90's.

For a demonstration of JsDOSBox running a shareware game go to http://jsdosbox.appspot.com. And running DOS demos at http://retropcdemos.appspot.com. Chrome browser is recommended. If your browser supports WebGL append /JsDOSBoxTest.html?screen=WebGL to get some extra performance at the expense of visual quality.

To see a more general x86 PC emulator which boots FreeDOS and Linux see my other project at http://sourceforge.net/projects/jspcemulator/. It was mostly coded in 2010, src uploaded early 2011. Hasn't seen much changes since mid 2011.
