The first computer I used had floppy disks, but when I was a kid my older brother used one with audio cassettes. I have no idea how much memory those computer have - I'm not actually sure about the one I have now, heh. I remember my dad carrying around the punch cards when I was younger but I don't know if those were for a computer he actually used or if they were just used ones around at work that he would use as note paper.
