Workstations for computer graphics applications require a number of I/O devices, which normally include a CRT screen, a keyboard and a tablet. The tablet is used as the electronic writing surface. and the screen displays the graphical picture. It is often desirable, and sometimes necessary, to have a second CRT screen to display system information, while preserving the graphical picture on the main CRT. Frequently, too, overlays are placed on the tablet to define certain areas, for example, as an alpha-numeric keyboard.
