TR computer
The TR computer was the only computer at Tranquil Repose inaccessible to "the Great Healer" Davros, requiring a security code. It had a foppish computer voice that had been installed by a truculent engineer in a moment of mischief, always greeting Lancelot Takis with "How do you do, Mister Takis? And what is your pleasure?" and always ending their interactions with "You're welcome." (PROSE: Revelation of the Daleks)
Takis asked the computer for an ETA on President Vargos's ship, and was shown transponder codes for the ship as well as a Dalek freighter directed to Necros. (TV: Revelation of the Daleks) He later accessed the TR computer again with August Lilt shortly before the Daleks arrived. (PROSE: Revelation of the Daleks)
