Computer sphere

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

During his retrieval within 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) The Time Lords were aware that the Daleks used the computer sphere to store data about enemy movements, and believed that it preceded the establishment of the Dalek hive mind.
