I mean, I keep a computer around running Windows 3.11. Some people enjoy the challenge of running old software on old hardware, rather than in emulators—it’s fun. 25 years old definitely qualifies as “retro.”

But also “you didn’t explain” is, again, kinda condescending—why should OP have to justify themself to you? You couldn’t imagine any reason they might be asking about Windows 98 other than that they were wrong and in need of correction? If that were so, why would GNU bother maintaining the old-gnu FTP directory?

Hmmm. I typed it by hand, so let me check I didn’t mess it up

Edit: Ha, yep. s/.old/.org/. I’ve fixed it.

Looks like https://ftp.gnu.old/old-gnu/emacs may have what you need. There’s a windows directory in there too.

This old FAQ mentions that (at the time) Emacs 20.7.1 was the latest version, and describes it working on Windows 95/98/NT. I do see 20.7 on that FTP server.

Good luck! (And may God have mercy on you :D)
