I used to have an Atari ST, i love that little green crappy desktop for irrational reasons
Didn't the ST run GEM? Now that I think about it, I believe GEM could run on a bunch of different computers. I'll have to see if I can find a version to install on one of my banger laptops.
Yes it did, and yes it could, although I never saw it run on anything else - or if I did i didn't recognise it...
AFAIU the atari version was a little more capable and a bit more fun than the other versions, due to Apple suing DRI and crippling later versions to comply with Apple's demands, yet somehow Atari was excluded from those demands since they bought rights to the source code for further development so continued with the original concept.
You can definitely put together a GEM on top of FreeDOS stack.
I got some janky 486 laptops for note-taking in university and swapped between that and OS/2 3.0 with its rudimentary pack-in wordprocessor. PC/GEOS would have been even better, but was not readily available at thwe time, as I think it was still a commercial product targeted towards schools using hand-me-down PCs.
