This site has a good description of how to do a hardward converion for a cable
connector. I spent about 10 minutes browsing the site. The content is good with
photographs and drawings to describe the electronics used in the conversion.
This is a good addition to a course about cabling systems. The materials were
easy to use, since it is simply an html site.
