Apple FileWare

Fileware diskette

FileWare floppy disk drives and diskettes were designed by Apple Computer as a higher-performance alternative to the Disk II and Disk III floppy systems used on the Apple II and Apple III personal computers, though it only ended up being used in the original Apple Lisa. The drive is named Apple 871 in service documentation, based on its approximate formatted storage capacity in kilobytes, but is most commonly known by its codename Twiggy, named for a famously thin 1960s fashion model.
