A time independent controller for a novel cassette changer is shown. A cassette changer including a plurality of limit switch inputs (210) and means for detecting occurrence of a failure during a change cycle.

In one disclosed embodiment a read only memory (465) determines the controller state (461-463). Apparatus (426, 427, 450) which is responsive only to the limit switch inputs closing in a pair wise proper sequence is also shown.
