I've launched an emulator for working on OS/Programs at the link in the first post. While the UI is a work-in-progress, with this "working" I should be able to start on a proper OS to use with the architecture. If anyone ends up using it, let me know how it turned out.
Just released version 0.5. Now with Callbacks! Turns out Rhino's continuations cause quite a few things to be broken, so now computer.invoke is handled with callbacks and an event loop. Check out the wiki for more info.
Documentation now in the post. Checkout the wiki. Good point. Unfortunately, the lack of documentation extends from the lack of implementation. http://ocdoc.cil.li/tutorial:custom_oses should be a good place to start, since that provides the grounds for OS creation, but otherwise, the only real difference from, say Node.js, is the inclusion of the components object, and the computer object. I'll be sure to post a link to better documentation when I get around to making it.
