Debating on putting bad tech on your resume.

I frequently find myself going back and forth on this. I've worked with a lot of technologies over the years, and some of them are pretty bad for my career. Notably I have a year of VB6 and Microsoft Access. I've omitted these technologies from my resume out of fear of being label "out of date". But I suppose there is an argument for being upfront and honest about the work you have done.

What do you think? Does bad tech go on the resume? When do you draw the line of what goes, and what stays?
