         With the optional TV Interface Unit, instructors can lead their    
          class - and teach in color! - using a standard TV monitor.        
         This special teacher's model performs exactly as the standard unit 
          with the addition of a NTSC video output that you can connect     
          directly to the video input of any conventional TV set.
