"Unix Implementation" paper in HTML

So, I'm hoping someone can help me with a minor mystery. At same point, I ran across, and saved, this: http://ana-3.lcs.mit.edu/~jnc/tech/pdp11/BSTJ_July-August_1978.htm which is a very nice HTML recreation of the famous first BSTJ Unix issue. Notice that it contains links to online HTMl versions of two of the papers; the basic Unix paper (the one that was famously in CACM), and "UNIX Implementation" by Ken Thompson. Alas, I appear not to have downloaded and saved the 'Unix Implementation' paper; I have searched high and low on my machines, and no sign of it. Double alas, because it doesn't seem to be online anywhere either! I have found a PDF version online, and also the NROFF source, but not this HTML version. I just don't recall exactly where I found this, so I can look in the Wayback Machine for the HTML. I _thought_ it might have been from Ken or DMR's Web page, so I found both of them in the Wayback Machine, but in sampling them both over the years, neither one seems to have had this. (And the Wayback machine doesn't have a search function that I know of, to search for it directly.) So does this page ring any bells for anyone, or alternatively, has anyone saved the HTML version "Unix Implementation"? (Yes, I know it's no biggie, with the PDF version available, I'm just being anal.... :-) Noel
