Any good anagrams for orac?

Orac is a fictional character from the British science fiction television series Blake's 7. The voice of Orac was Peter Tuddenham, except in its initial episode where he was played by Derek Farr. Orac is a highly advanced supercomputer developed by the scientist Ensor, brought aboard the Liberator by Blake and the others at the end of the first series. Ensor was a particularly irascible character and Orac, as his creation, inherited some of his character traits. Orac is extremely terse and short-tempered and frequently talks down to the humans. Rather than a personality or character, Orac is an ego and often refuses to answer questions he deems too simple. Avon often lamented that Orac was too valuable to dump. Orac is activated by a "key", which is removed by the crew to shut him up if he prattles on too much. This egotistical attitude, and the potential absence of the key at any given time prevented the sloppy plot device of "Orac to the rescue of every problem". There is evidence that Orac was still functional in the "off" mode, as his response to activation would be one of impatience, "What is it now?" indicating that he was performing other self-preoccupied activities.
