Device Side Data develops and sells innovative computing accessories.
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.
