## REQUIREMENTS OF GRAPHICS DISPLAY DEVICES FOR GRASS

Below are the requirements of any graphics display device used to with GRASS.

Graphics Library:

The system should have a compiled graphics library such as GKS or Sigcore.

Color Graphics Monitor:

The color monitor is important for displaying GRASS graphic outputs. It should have a minimum of 256 color display. It is used in conjunction with a mouse. Some systems allow more than one color monitor to be utilized by the same processor, although additional monitors will be competing for CPU time.

Alphanumeric Monitor (CRT, terminal):

The CRT is used to enter GRASS commands. This keeps the entire screen of the color monitor available for graphic display. On some systems, the same unit serves the functions of both the graphics display device and for entry of commands. Machines running windowing systems, like X Windows, have this capability.

See the monitorcap discussion for further information.
