Realtime IE JavaScript evaluator available?

I was wondering if there's such a thing like an online IE 8 JavaScript parser? Something similar to this Realtime JavaScript Evaluator, with a console.

Something to help test what works/doesn't work with those older browsers.

I know of tools like BrowserStack, which let you load a virtual browser, but that's a bit more troublesome than what I'm thinking of as you can't copy and paste stuff from your computer to the virtual computer, along with other small issues.

As shown below, BrowserStack does actually allow you to copy+paste into an IE 8 session.

I've pasted some sample JavaScript into the console window and it also comes with Firebug Lite.
