Then again he's also about a decade late with the next book
If you want output, Stephen King has used many processors, he doesn't care aparently as long as he can focus. Brandon Sanderson uses Word. The tool doesn't seem to matter.
Quite often solicitors have stuff on 3.5" or even 5.25" floppies that need read, converted from WordPerfect into something modern, and delivered as maybe a PDF or Word Doc.
Fortunately, solicitors tend not to be short of money (that they bill their client for) so they can often find "a guy who knows a guy" who can get that precious floppy onto a USB stick. Occasionally I am the guy who the guy knows, and it buys me the odd case of reasonably-priced wine.
Usefully showing end-of-line markers. I remember thinking compared to dec-10 ROFF (which iirc proceeded nroff etc) it was both simpler and harder.
Used it, never liked it. Ed was the way.
I'm not sure how I would get my files I create off the device since USB support isn't really a thing.
groff file.troff -step -k > file.pdf
If any, check Groff with Mom macros, with does what you need with ease:
Online manual:
https://www.schaffter.ca/mom/momdoc/toc.html
For groff+mom, you would run:
pdfmom -step -k file.troff > file.pdf
For instance, get https://www.schaffter.ca/shared/groff-and-mom.mom and the style file https://www.schaffter.ca/shared/groff-and-mom-style.mom and place them in the same directory. These are just examples.
Next, run:
pdfmom -step -k groff-and-mom.mom > out.pdf
I think the below-mentioned Pocket 376 might have one soldered-on already.
Or just run joe as jstar and close enough, maybe? I use joe for mostly everything, but I never used WordStar (well, I ran into it once)
It's still early and I'm struggling to write more than a few lines at a time. Not surprising from how I've been commenting "witty" one-liners in comment threads for over a decade. I expect being able to write long-form with no backspacing will need a lot of time to learn.
But I want to take back my attention. If there's one thing I've learned in the last decade, is that one's attention is a precious resource and it's time to be more deliberate in how I spend it.
I'm not sure that I could work that way now, but it was more deliberate. Less 'drive by' thought.
"Our Writing Tools Are Also Working on Our Thoughts"
(I'm talking essays for University here not deathless prose).
I’m trying more and more to not spend tokens on things that don’t help (social media), etc.
Only start editing when a substantial piece is ready. Clean up some wording, rewrite a paragraph or two.
Even then, don't overdo it. There is always something to improve, you'll never be done that way. Good enough is good enough, hit publish and go on write the next thing.
Each to their own, and of course finding an optimal writing environment is a very subjective thing -- but it's not like there aren't modern distraction-free writing interfaces that exist.
In retrospect the quality, quantity and look and feel of the documents I created remained exactly the same.
GUIs were invented by the Xerox PARC team early 1970s, the IIc (I have one sitting on my desk :) was 1984. Totally beside your point so I apologize. I only mention it because PARC deserves a huge amount of credit.
