Ha ha, good one. I never had to do it (or had the privilege of doing it, depending on one's point of view), but saw it being done some (as a junior), for internal or client presentations at companies where I worked earlier. Another name for it was "transparencies", IIRC. Ugh. Fiddly stuff. Something like the difference between writing articles or books on paper (or typewriter) versus using a wordprocessor or text editor, with all the attendant slowness and rework in the former cases.
It's amazing how many of these integral tools that we've relied on for a long time are maintained by selfless individuals in their basements. Fantastic.
