xu1541 is a Commodore floppy disk drive to USB adapter based on the design by Till Harbaum and Spiro R. Trikaliotis. It connects a variety of CBM drives (1541, 1541-II, 1570, 1571, 1581, SX-64's internal floppy disk) to USB-equipped PCs running Windows, Linux or Mac OS X. This allows for easy transfer of disk images to and from these devices and helps you preserve your old data.
