I've just read that Sony plans to discontinue the manufacture of 3.5-inch floppy disks. [Update: a more complete tribute to the floppy disk is over on Geek News Central.]
The announcement made me nostalgic for the days when we shipped The SAS System on floppies. I don't think we've done that since the Version 6 days (for Windows and OS/2). I'll be honest; I don't remember how many disks were required for a typical Base SAS installation. After reading the old 6.12 system requirements I'll bet that it was a bunch, and the SAS users in those days would spend a lot of time switching out disks during installation.
Thank goodness we now have electronic software download. You can now get your software via the Internet. And back it up to about 7,000 floppy disks for safe keeping, if you want.
