Slightly off-topic, but back in the day "V86" (or "VM86") used to refer to the 80386 CPU's inbult 8086 hardware virtualization mechanism: https://en.wikipedia.org/wiki/Virtual_8086_mode

Didn't Fabrice do something very similar something like 3 to 4 years back ?

#13Interestingly the popup about copy.sh having control of the cursor was somehow overlaid above my Firefox titlebar, tabs, and addressbar. Didn't know that was possible.

Are you thinking about JSLinux? http://bellard.org/jslinux/
It does sound similar to the underlying PC emulator (http://bellard.org/jslinux/tech.html) and Bellard does indeed list v86 in section "Similar Projects (Several other PC or Linux emulators are now available)"
The v86 project's initial release was late 2013 (https://github.com/copy/v86/commit/8180d49f24833fc6cc05a9025...) about 2 years after Bellard's (http://bellard.org/jslinux/news.html)

#15Not compatible with Firefox... This error in JS console:
TypeError: a.table[b] is not a function
Works in Chromium though.

#16Really cool, but perhaps the title should indicate that this is an emulator that works in the browser? Perhaps a short description at the top of the readme before the demos?

It's the pointer lock API:
https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Loc...
The browser tells you when a page calls requestPointerLock(), and tells you how to exit it, similar to the fullscreen API.

#18Booting Windows 98 in Firefox on a smart phone is a real tangible reminder of how far things have come in my lifetime.
Re: V86 – An x86-compatible CPU and hardware emulator
#19How much work would be required to allow network access from one of these emulated machines? Could it be done over websockets (via a proxy)? EDIT: After reading the docs, it seems that this is already implemented (via websockets, too!): https://github.com/copy/v86/blob/master/docs/networking.md
Also, a few of the live demos have networking enabled.
But they're not internet connected, are they? I tried `ping 8.8.8.8` from each of them without any luck.

through multiple abstraction layers no less!
