Hi, some links are broken since .... then (10 years ago)

Hi, I hope this issue finds you doing alright. It must have been about 10 years now since your study made on SECD and this repo for some of the resources you found relevant, which I appreciate very much as I too, am doing some learning on this subject.

So, there are two links that I have found broken:

• (Forbidden) Lecture notes on the SECD machine: http://webdocs.cs.ualberta.ca/~you/courses/325/Mynotes/Fun/SECD-slides.html
• (Not found) An SECD implementation (in what I assume is Common Lisp?): http://ugweb.cs.ualberta.ca/~c325/secd.lsp It may be helpful (maybe just me) to strike them through, to reflect that status.

Happy for a PR if you can suggest fresh links :-)
