Computer sphere

The Computer sphere was a spherical white globe of Dalek design.

During the Dalek-Movellan War, the resurrected Davros was given a computer sphere that contained information on the Dalek Battle Fleet. It contained all the details of the situation; with the data being checked and supervised by the Dalek Supreme. Once Davros consulted the information in the sphere, he hatched a plan through which the Daleks would gain dominance over the Movellans.

After examining the information, Davros found it to be a concise report on a fascinating problem. (TV: Destiny of the Daleks)
