Commodore 2031 Disk Drive
The Commodore 2031 is a single unit 5¼” floppy disk drives housed in and using the IEEE-488 interface to connect to the PET-series of computers.
Like all Commodore disk drives, these drives were “smart” devices. They had their own processor, their own memory, and their own disk operating system. Basically, a Commodore computer and its disk drive resemble a network!
