What a coincidence, I was just thinking about how nice it would be if I could start a minimal javascript linux with toybox and start spacemacs with it (< 64M) and a small mounted filesystem somewhere.

Win 3.11 in the browser would be nice too, there is a whole ecosystem of apps. Windows95b would be slower, but still faster and smaller then Windows98.

I wonder how fast civ1 would run on freedos here.

95 in the browser has already been done (by me): https://win95.ajf.me/

That uses Em-DOSBox, which is more limited than v86 (which the OP uses) in some respects. I think v86 is loading hard disk sectors on-demand, which is pretty amazing compared to Em-DOSBox which has to download a massive disk image. On the other hand, Em-DOSBox has sound support!

The Internet Archive has 3.11 in the browser: https://archive.org/details/win3_stock (there's also various 3.x games as well)

This also uses Em-DOSBox.
