How do I get a cached webpage?

This web address: http://learn.sdstate.edu/nursing/Medication.html leads me to a big nowhere, but isn’t there some way I can find a cached copy of what used to be there? It looks like just what I’m looking for. (Or maybe it’s not, but I’d like to get a peek at it and see.)

I found the apparently outdated link at another site.

The Wayback Machine is what you want: http://web.archive.org/web/*/http://learn.sdstate.edu/nursing/Medication.html

Thank you!
