That is correct. As I stated: "Archives of the following page are accessible via the Wayback Machine"
The 'Wayback Machine" is very useful to view webpages that are dead and gone. You can find it at:
When you get there, enter a URL e.g. http://www.dct.com/~johnm/Pmi.html
and it will show you the number of times and the dates that webpage was archived.
Many of the snapshots are 'wild goose chases' but the snapshot taken on April 28th 1999, for example, returns a page with information on it. Unfortunately, download links that are ftp sites on that page lead to nowhere. However, I have found in the past that knowledge / keywords gained in this way can often lead to an ftp archive or mirror elsewhere which is still accessible.
