Yes! It's practically my bible now -- I even printed a copy through printme1.com so I can have a bound copy to flip back and forth through ( and dog-ear, tag pages, etc.) I reference other implementations and z-tools to gain insight on changes in memory, objects, etc.

I'm writing blog posts on my journey - detailing each instruction and any nuance with each one, as well as the object structure, z-text and misc. I hope to post it here one day.
