crashes always: HTML 4.0

Chapter  3."On SGML and HTML"
at the address

 http://www.w3.org/TR/REC-html40/intro/sgmltut.html

crashes always! Ive been trying it for 5 (five) times and two days and that
page crashes always. Other chapters = no problem. Anybody knows why? Is
there any chance to see that page at all?

Thank you.
