"Architecture of Python" was removed ?

[cr999]

I found the "Architecture of Python" ( http://wiki.cs.uiuc.edu/cs427/PYTHON By Jim Jackson, Kar-Han Tan )is very useful for my understanding of the Python's architecture. But I found the link is not link to that document today. It seems that the document was removed. Who knows what happened?

Does anyone here have a copy of that document? Or who can tell me what is the email address of Jim Jackson or Kar-Han Tan. 

Thanks a lot. 

Best Regards. :)
