3. Display unit, light pen, and typewriter. The light pen was common 
before the mouse became popular. A fiber optic cable runs from the hand-held 
device to a photo-multiplier (very sensitive light detector). Because the display unit scans and can plant a dot every microsecond, the time of day when the pen sees light tells the computer the coordinates of where it is pointing.

4. View of the cabinets from the side. As I said before, about the size of three refrigerators paced side by side.

Please look large.
