Central Control Computer
The primary monitoring and control system for the UNIT nuclear drilling project, located in Central Control. This computer displays real-time drilling progress, issues catastrophic warnings, and manages shutdown countdowns. During the crisis, it flickers with urgent alerts as Liz Shaw verifies the Doctor's warnings, while Stahlman and Gold ignore its signals. The Doctor and Greg Sutton interact with its systems in the Drill Head, where sabotaged wiring panels disrupt its readouts. The computer announces the countdown to penetration zero, confirms crisis aversion with 35 seconds remaining, and declares all systems closed down after the Doctor halts Stahlman's operation. Its outputs are monitored by the Doctor, Greg Sutton, Liz Shaw, Petra, and Sir Keith Gold during the tense shutdown sequence, with its final success signal marking the resolution of the crisis.
