HDDD A2 is a modern product for the Apple II family of computers. While the Apple II computers haven't lost their charm even after few decades, their 5.25" drives and diskettes are beginning to show the signs of age and wear and getting scarce. HDDD A2 tries to fill this gap and still keep the retro feeling by making a standard IBM PC 3.5" HD floppy drive and 3.5" HD diskettes a direct replacement of the venerable Disk ][ drive.

Installation is as easy as disconnecting the Disk ][ drive and connecting HDDD A2 to the disk controller. Supports all Apple II operating systems (DOS 3.3, ProDOS, UCSD, etc.) with 140KB capacity and side selection via jumper or user-provided external switch. Possibility to transfer all unprotected and many protected 5.25" titles to 3.5" media for backup purposes or everyday usage.
