In-flight systems were governed by the ship's central artificial intelligence computer, MU/TH/UR 6000 (known by the crew as "Mother"). A backup 2.0 terabyte mainframe would come online should Mother fail, while a third tier of automation could sustain vital systems in the rare event of a failure in the backup CPU as well. Despite the extensive computer automation aboard the CM-88B, a human crew was still required for more complicated docking manoeuvres at each end of a transit.
