I’m still amazed that you found it. I searched for several hours and couldn’t find it at all.
I was about to just stop at a library to find a copy.
I don’t want to say what lead me to it, but it took searching through a lot fo titles and phrases. It was not at all intuitive. But I have the source bookmarked now :) and anything I research I also download. Make a habit of downloading everything. More is being scrubbed than I ever would have believed.
