You must be old as dirt also. I had to use punch cards in college in the ealry 1970's. The Univ of WI in Milwaukee didn't even have their own computer. You gave them the punch cards and they shipped them to Madison every night to run on the "big" machine. Your handheld calculator probably has more memory than that computer did. We did have a neat PDP-8 that used 1" tape as a memory.
