The Disk II is Apple's first disk drive. Its Floppy Disk Subsystem was a 5¼-inch floppy disk drive designed by Steve Wozniak and manufactured by Apple Computer. The Disk II was designed specifically for use with the Apple II personal computer family to replace the slower cassette tape storage and cannot be used with any Macintosh computer without an Apple IIe Card.
The Disk II uses the Disk II Interface Card to connect to an Apple II computer. Disk II drives are attached directly to the card by a ribbon cable, unlike later generation Apple 5.25-inch drives that use a 19-pin connector. The Disk II Interface Card supports up to two Disk II drives at a time. The Disk II has a sturdy metal case that is painted beige with a black face. It can support a monitor but it is unadvisable to place a monitor on top of two Disk II drives because a heavy monitor can cause the case to bend down and affect the drive mechanism.
