I was in a similar position with classic ASP/Coldfusion and VB6. What I did was rewrite my resume to target the things I did like build reporting engines and dynamic web pages. I mentioned more of my impact on my job and accomplishments over what technologies I knew. I highlighted more general skills like SQL programming and downplayed other language specific references like VB5/6. I landed a job no problem. I spent the week leading up to the job studying up on the tech they used and was ready enough.
