I know this is gonna stretch you're imagination, but in the days before PowerPoint things went like this. You sketched out a presentation on paper, or maybe an HP9814 computer with a plotter. With the plotter's output, you could make color overheads for small audience presentations. But the larger group presentations (50-250+people) were all color slides in glass mounts. You and your Kodak carosel flew off to various cities to give the presentations. You brought the script and the slides in your carry-on luggage, because you were worthless without the slides. You had to finalize the presentation 2 or 3 days before departure so they could create the slides. It's all PowerPoint now. Regards, Bob S.
