Happy drives

Happy drives are series of disk drive enhancements for the Atari 8-bit and Atari ST computer families produced by a small company Happy Computers. Happy Computers is most noted for the add-in boards for the Atari 810 and Atari 1050 disk drives, which achieved a tremendous speed improvement for reading and writing, and for the ability to "back up" floppies. Happy's products were among the most popular Atari computer add-ons. They were still in use and active in the aftermarket as of 2009.
