  FWIW Amazon lists used copies of ISBN-13
978-0932376121 around $100. I
 bought a used copy a couple of years ago that turned out to be an
 ex-library copy. Don't think I paid too much at the time. Still haven't
 gotten around to looking at it much. 
For most hobbyists, even $100 is too much.  I was simply astounded at the
chutzpah of the seller--right there on the Amazon list--who was asking
nearly $1500 for a copy.

Well, I was going to point that out to my friend Ralph, but I see that
it is a different book with the same title, by one Stephen Longo, which
has been stolen.

  There is a similar document online at Columbia with
parts written by
 Ralph Gorin 
<http://www.columbia.edu/kermit/ftp/dec20/assembler-guide.txt> 
Rather, adapted from Ralph's early course notes (he was teaching the
class at Stanford for a few years before the book was published) by
Frank da Cruz and Chris Ryland.  I know that Frank and Ralph were
friendly, so I'm not surprised that Ralph shared his notes.

  I think this is the same file, but in HTML-formatted
with one page per
 chapter: 
No, that's an HTMLized version of the INFO file that accompanies the
original EMACS (the one written in MIT AI Lab TECO for the PDP-10).
So David, there are alternatives to the Gorin textbook.  I simply prefer
it for paedogogical reasons.
