Doc and Marty chop through the planks and rocks. They get through and see the DeLorean, covered in a sheet. Doc sighs with astonishment.

Doc: It's been buried here for 70 years, 2 months, and 13 days. Astounding.

Later, Marty and Doc are repairing the time machine. Marty is reading 1985 Doc in 1885's instructions. Doc stares at some parts through a magnifying glass.

Marty: "...As you can see, the lightning bolt shorted out the time circuit control microchip. The attached sh...sh..."

Doc: Schematic.

Marty: "...schematic diagram will allow you to build a replacement unit with the 1955 components, thus restoring the time machine to perfect working order."

Doc: Unbelievable, that his piece of junk could be such a big problem. No wonder this circuit failed - it says, "Made in Japan."

Marty: What do you mean, Doc? All the best stuff is made in Japan.

Doc: Unbelievable!

That night, Marty and Doc are back at the cave with a tow truck which they're loading stuff onto.

Doc: You know, when I was a kid I always wanted to be a cowboy. Now, knowing I'll spend my future in the past it sounds like a wonderful way to spend my retirement years. It just occurred to me - since I end up in 1885, perhaps I'm now in the history books. I wonder - could I go to the library and look myself up in the old newspaper archives?

Marty: I don't know, Doc, you're the one whose always saying, you know, it's not too good to know too much about your own destiny.

Doc: You're right, Marty. I know too much already. Better that I not attempt to uncover the circumstances of my own... future. Copernicus! Come home boy!

Marty: I'll get him Doc. Copernicus!

Copernicus, off stage, is whining.

Marty: Come on, let's go home, boy.
