Blast from the past! I remember reading about this a long while before life was greatly enhanced and simplified and also terribly blighted by the hand-computers. I was into paper notes for about a year, just at the very beginning before phones came and I lost interest in pretty much all analog tech. One thing that was cool about that era was the amount of variety. Now that multi device sync exists, notetaking is a very hard technical problem, but before that expectations were lower and people could invent all sorts of systems that were totally practical by the standards of the day. Of course I greatly prefer the modern system, but the aesthetics were pretty cool.
