And WordStar, if I could have found it.
Yes, The Evil One will let you have version 5.5 of its ancient Word application gratis, right here. And yes, in DosBox (and probably other emulators), it works great.
WordPerfect, or WordStar, well … you might have to search around to find them.
I know these are real stretches to suggest they are “lightweight or minimalist software for Linux,” but I’m willing to loosen the definition.
And it might also be important to note that from a historical point of view, programs like this still carry some influence into the software of today.
I don’t suggest you fall back on a copy of DosBox and Microsoft Word just to edit your .bashrc file, but I have made stranger leaps in the name of science.
And hey, if that’s what works for you, I can find no fault.
