I do remember the bad old days, when even a leased line was insufficiently fast or reliable to send a quantity of data. I recall many times taking the "noon balloon" out of San Jose with my Samsonite carry-on case and not so much as a toothbrush. On arrival, turn the contents of the case over to someone waiting at the gate, and catch the next flight home with an empty case.
My case, which I still have, comfortably accommodates six 10.5" reels of tape. I remember flying on an USAF general's plane with several 844 disk packs. One time, I forgot my B-area badge, so the general gave me his. Nobody saluted, however. --Chuck
