Okay, so I did the work and have added links to the freeware I use as a separate category.
In addition, I’m uploading to my MediaFire folder HP Calc, a Hewlett-Packard math program for Win 3.1 that has a very easy to use equation editor. I wish I could change that hideous green it has, though.
Also AnaGraph, a simple graphing program no longer available online (that I could find, anyway).
Actually, I’ve never used either of them in my VMs work, but they are very useful for a different hobby– Long Delayed Radio Echoes.
