Le Verrier computer

A computer was installed on the Le Verrier space station in the 38th century. Its functions included the locking and opening of doors. (TV: Sleep No More)

History
At some point before the outbreak of the Sandmen, after a Maha Shivaratri/Oshogasu/Christmas party, a crewmember reprogrammed it not to allow any person entry to a room until they sang the song Mr. Sandman. The computer found it very amusing.

It was destroyed when the Doctor disabled the station's gravity shields and sent it falling towards Neptune. (TV: Sleep No More)

Behind the Scenes
The computer was voiced by Nikki Wilson, who was the producer of the TV episode in which it appeared.

Its tone, voice and personality are very similar to those of GLaDOS from the video game series Portal.
