That software understood the difference between data and presentation.

I used that for a few years outputting slides to transparencies on a pen plotter. There was some other pre-Powerpoint program I used on PCs back then too but don't remember the name--may have been Lotus Freelance. (And a minicomputer-based program before those.)

Mirage was one too. It was hard to use.

Those were the days when you had all manner of different word processing and graphics programs (among other things--though Lotus had mostly standardized people on 1-2-3 before Excel and Microsoft Office came along).

It's been decades since I heard of Harvard Graphics. Was part of my toolkit with WordStar, Lotus 123, FoxPro and NC. MS C6.0, MASM, CodeWarrior, an editor called Brief on the dev side. Good times.

Wow, Harvard Graphics apparently stuck around until 2017 - http://www.harvardgraphics.com

I remember getting a giant box copy of it when a company my dad worked for was shutting down, it was years after it had been released but it had a massive manual and was pretty powerful.
