Device Side Data's flagship product is the FC5025 USB 5.25" floppy controller. The FC5025 plugs into any computer's USB port and enables you to attach a 5.25" floppy drive. Even if your computer has no built-in floppy controller, the FC5025 lets you read those old disks. And it's not just for IBM PC disks – it also understands formats used by Apple, Atari, Commodore and TI, among others.
