Apple and the Floppy Drive
From the site:
"The histories of Apple Computer and the floppy drive have been intertwined ever since Steve Wozniak hacked together a workable floppy drive controller hours before the start of the 1978 Consumer Electronics Show in Las Vegas.
In this site, we will explore how Apple's choice of the floppy as the storage medium of choice for the Apple II and later, the original Macintosh influenced the development of floppies as an industry standard.
We will follow Apple's use of the floppy up to May 1998, when the company's dramatic omission of the floppy drive in the iMac demonstrated the ultimate rejection of the floppy as a viable method of data storage."
