It is also possible to connect one of the older style Connectix/Logitech
QuickCam cameras:

 - QuickCam Greyscale Camera for Windows (parallel port)
 - QuickCam Color V2 Camera for Windows (parallel port)
 - None of the newer cameras work, since Connectix/Logitec does not
   disclose the camera specs.
 - For connecting a QuickCam camera, plug it into the parallel port
   connector of the EyeBot. For power supply, Connectix/Logitec has
   a PC keyboard conncector, using only a single wire. Cut this
   keyboard cable and connect it to the power pin on the top side of
   the EyeBot.
