We asked my dad about it and he remembers it vividly, because he's also a Dodger fan:
"I remember it well. Watched it at home. I had the Bills game on the big TV and the Dodgers/Astros game on the small TV, in the great room. The LAD game had post season implications, as they needed to win to force a divisional play-off.
Believe it or not, Haslett’s INT occurred almost EXACTLY the same time as when Ron Cey hit a 2 run HR (Garvey on) in bottom 8 to give the Dodgers a 4-3 lead, the final score."
