If you're bored (or your code is still compiling), you can also try:

SerenityOS: http://copy.sh/v86/?profile=serenity (one of their developers contributed PAE support to v86, which is extra cool. I believe it contains their own browser.)

ReactOS: http://copy.sh/v86/?profile=reactos

Haiku: https://copy.sh/v86/?profile=haiku

9front: http://copy.sh/v86/?profile=9front

Android: http://copy.sh/v86/?profile=android

KolibriOS: http://copy.sh/v86/?profile=kolibrios

HelenOS: http://copy.sh/v86/?profile=helenos

Oberon: http://copy.sh/v86/?profile=oberon

QNX: http://copy.sh/v86/?profile=qnx

Windows 95 with IE 3: http://copy.sh/v86/?profile=windows95-boot

Windows 98 with IE 5: http://copy.sh/v86/?profile=windows98 (run networking.bat)

Windows 2000 with IE 6: http://copy.sh/v86/?profile=windows2000 (run networking.bat)

v86 running in v86 (the inner one is running in node): https://copy.sh/v86/?profile=archlinux&c=./v86-in-v86.js

As well as most BSDs and Linuxes, as long as they still have i686 support.
