Usagi Electric (Electric Bunny in Japanese) is visiting us. And I have the very floppy drive his Centurion minicomputer is missing. In this episode, we repair the head actuator brake with a professionally printed 3D part, and demonstrate how to realign the drive with a professional alignment diskette as well as without it. There will be professional bunnies at the end, promised.
