Welcome to The Trailing Edge

This site is devoted to computing technology which has been left behind by the rapidly advancing Leading Edge of computing. Many interesting and useful systems have been forgotten with the mad rush to stay on the Cutting Edge and maintain the high sales of hardware and software companies. While we too like to have the latest and greatest, we don't want people to forget the legacy which lead to today's systems. Many of these older systems were once considered part of the Bleeding Edge but most people know little if anything about them or just dismiss them. If you have some item related to these old systems that you'd like to clear out or just want to say hello and share some story about them, you can email me at dlw@trailingedge.com.

If you are looking for the used PC store in Canada, this is not it. What you are looking for is here.
