On September 1st, 1980, Apple introduced the world to the Apple Disk III, an external 5.25″ floppy disk drive designed specifically for use with the Apple III computer. This new addition to the Apple lineup was manufactured and sold by the company until May 1st, 1984, making it 42 years old today.
The Disk III was a variation of the previously released Disk II but featured a modified plastic case and a proprietary connector. Despite these differences, the drive mechanism inside Disk III was identical to that of Disk II, making the two drives interchangeable with some modifications.
Although Disk III has been discontinued for over 42 years, it remains a significant piece of Apple’s history and a reminder of the company’s early efforts in the world of personal computing. The Disk III was a crucial component for the Apple III and Apple III Plus computers, allowing users to store and transfer data in a time before the widespread use of hard drives and USB drives.
As technology continues to evolve at a rapid pace, it’s important to remember the innovations of the past that have paved the way for the devices and platforms we use today. The Apple Disk III may be long gone, but it will always hold a special place in the history of Apple and the personal computing industry as a whole.
