Haha! Yes, I do. My dissertation occupies nine of them, and I had them numbered like that.
Actually, I also remember the five-and-a-quarter-inch floppies as well. They were quite floppy. When the 3 and a half inch floppies came out I thought they were so cool. Man, I gotta get me one of them 3.5-inch drives. High tech.
I'm not quite old enough to remember punch cards. Well, I've seen them, but I really don't ever recall a time when the CS majors would walk around campus carrying them. That was long before me. I just remember the big boxes holding the 5.25-inch floppy discs.
I also remember my first dial-up modem, about 21 years ago. I'd dial a number and it would make all these loud boings and scratchy sounds, and about half the time I'd actually get connected. If I actually got a connection, I'd log on to a a mainframe and within five minutes or so I could be opening an email message.
It seems mostly that we just get more and more dependent on technology. I remember when I could take a month-long vacation and not be bothered by anything in the civilized world. I can't imagine that happening now. We also insist upon replacing everything that's a few years old, even when it still works. None of this is necessarily a positive development.
