Microputer

A microputer is a small handheld device used by members of the Flock to bypass security doors. Sab loaned one to Tails when he visited the Chemical Plant Zone. Tails' confusing instructions to his microputer also helped him to defeat the robot Nutzan Bolt. He ordered the microputer to "Close the door. Close the door! Jolly well close the door!", leading it to open and close the door three times, crushing and then decapitating the robot.
