How can I find the first part of the ESE112 lecture on MSD systems?

[mech-eng]

I have found this link in the google but I cannot find its link in the site so that I can find it's first part.

Would somebody like to help?

http://www.seas.upenn.edu/~ese112/labs/MSDSystemLecturePart%202.pdf

It's a pdf document as you see but how can I find it by entering that website?

Thank you.

Maybe go back farther up the URL near the top and see if you can find your way back down?

http://www.seas.upenn.edu/~ese112/

I tried just changing the "2" to a "1" in the full URL, but that didn't work...

I found these two documents:

http://www.seas.upenn.edu/~ese112/labs/Lecture2Part1-Intro%20oCircuits.pdf
http://www.seas.upenn.edu/~ese112/labs/MSDPart1-ESE112%202007.pdf

I think the first one is mislabel and is actually 'Lecture One: Part I'.

I added 'site:http://www.seas.upenn.edu/' to my search to limit my results (Should work with all major search engines).
