How did they display the lecture slides on the in-classroom television in those days?


Most likely using overhead projectors.

It was quite some "fun" doing the printouts, and playing around to get them to display properly.


Good question and answer.

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.
