By plugging our 2120 circuit board to an unused USB Port on your computer, you can easily add up to 20 Toggle Switches to your homemade flight sim panel. Then programming the available flight functions found in FS2002, FS2004, FSX, FSUIPC and X-Plane to the 2120 board, you will have a simulator that will be the envy of the neighborhood. http://www.DesktopAviator.com
