The Master Control System was soon developed and introduced to the field . The system was not an AI, it was a highly sophisticated program, which monitored the structure's status and controled all of it's functions, even those as complex as Tiberium processing. The system also utillized various sensory and robotic repair facilities (and/or human a technician) to diagnose, plan and repair the building in an effective matter. The system's heart was a highly advanced and miniaturized mainframe, embedded in a sturdy frame of a console, which also served as the control terminal for the system. The consoles were usually located in highly secure locations within the buildings and more often than not protected by sophisticated weapon systems. Due to their appearance, they soon became known as Mast
