The emacs website has versions down to 22, but none of them seem to work correctly on Windows 98. I managed to get emacs 22 running, but it does not display correctly on screen. Only the -nw version runs correctly.
Is there any version that works well on the older OSes?
I used to use notgnu emacs on Win 98. Not really emacs (no elisp) but it was solid for me. https://www.geocities.ws/notgnu/ (GeoCities!)
new site notgnu.org isn’t working, you can possibly email the author for help if you want it.
