I have been reviewing several resumes we have for a new position.  I noticed that a few of them had many old programming language versions and old applications on their resume (e.g. SQL 4.2, VB5, Lotus 123, Novell).  This left their list of computer experience very long.  Do you keep it fresh?  Do you show your depth of experience even though you will never use that techology again?

When should you drop old technology on your resume?  By keeping old technology on your resume does that do any harm in getting hired?

I drop old technologies from the "technologies" section of my resume when I am no longer interested in working with them, or when they aren't being used anymore. I don't think long lists of technologies do anyone any favors.

I think technical depth is best illustrated through your work experience, where you can mention older technologies if you like.
