Better still might be a board that could connect to the drive heads and capture an analog signal, but I'm not sure if those exist. | |

But you still need the non-standard controller and that's where it gets easier to look for a Commodore drive and hook it up via IEC. | |

There used to be a board called the Catweasel which would interface between the PC and an old drive, and let it read just about anything, but I don't think it's been maintained in years. | |
