@birnim @thomasfricke @echopapa @ids1024 Yeah, I got into computing as paper was on its way out -- I learned to program on a Heathkit H89, and in my undergrad days we used VT102 and Wyse-50 terminals. My freshman textbooks straddled the eras.
I once used a roll of punchtape as a source of bookmarks that lasted for *years*.
