The Catweasel MK2 is still being sold for the Amiga and handles all types of disk drives from 3.5 to 8 inch. It can handle GCR and MFM reading C64 disks to CP/M. It connects to an IDE and Clockport and weird IO port on some of Jens' cards. While the are advantages to the Kryoflux hardware, the Catweasel lets you use a standard PC floppy as a DD or HD floppy.
