Meteor tracking system....

For those of you that know a little bit about computers, Go to about 44 minutes into this movie when they start tracking the next meteor right after the man says 6 meters wide and they cut to the computer screen pause the movie you can see that on the screen is a simple dos directory list which has NOTHING to do with meteors and is on pretty much every home computer at the time this movie was made. Funny thing is they type in DIR/W twice (look closely) which brings up the same directory and information over again just to make it look like the computer is actually doing something
