History computer
From Tardis Wiki, the free Doctor Who reference
The history computer was the computer-database of all Cyberman history, accessed by the Cyber-Planner during its attempted destruction of Earth in 2006. The Cybermen's attempts to take over Earth in the 1970s (TV: The Invasion) and in 1986 (TV: Attack of the Cybermen) were recorded as their "first" and "second invasions" respectfully. (PROSE: Iceberg)
