UniDisk 5.25

The UniDisk 5.25 reaplaced the Disk II. The drive mechanism is the same as the drive for the DuoDisk, the Apple IIc internal drive, and the Disk IIc. The UniDisk 5.25 uses a 19-pin connector and works with the Apple 5.25 Disk Drive Card. For each controller card connected to a UniDisk, a second UniDisk drive can be daisy-chained or connected to the back of the first. Unlike the Disk II, the UniDisk 5.25 is constructed of molded plastic, which actually makes its construction sturdier than its predecessor. The first version and the one pictured on this page was beige in color. Apple later changed the color to platinum (blue-gray). A9M0104 was bundled with an Apple 5.25 Disk Drive Card. A9M0105 shipped without the card.
