Catweasel and Catweasel Mk-II

Floppy Controller for the Amiga that allows the use of cheap PC floppy drives (both 5.25", 3.5" DD and HD) for reading Amiga and PC disks aswell as other formats. Designed for use with the A1200 and A4000. In the A1200 it connects to the clockport but still allows you to connect a HyperComm. In an A4000 it connects to the internal IDE port with a passthru for hard drives. The controller also contains sophisticated algorithms to help read previously unreadable disks.

PC disks are 2.15 times faster and Amiga disks are 1.3 times faster than using a genuine Amiga High Density Drive.

Supports floppy controller tape streamers with a thruput of 2MB/sec.

This versions connects to the IDE port in the A4000 and A1200 and still allows full use of the IDE port. The 1200 versions also supports connecting to the clockport on the motherboard, but please note, not all revisions of A1200 have the clock port.
