Directions for running the VR demos are listed below.

While the demos are interesting and fun, please remember to
be responsible and gentle with the equipment.

Note: Source code for the demos can be found at

For the demos listed below, follow these directions first:

  - turn on first 4 switches on the base unit under the
    small television (labeled "helmet" and "chair")

      cd /pub/demos/menu

  - execute the following command from that directory:

    (if the window has only one set of demos (SGI) then
     it's not the right one)
