As the OP here, I appreciate all of the responses. My original intent was just to save a little space on what I hope to be a fairly small board and I have to admit I hadn't really thought through some of the possibilities that evryone has brought up. I don't have any problems with providing test points for a 6 pin ISP adapter of some type. Along those lines I have done some internet searching but didn't come up with anything in particular. Can anyone provide more detail or even some links for some type of narrow pitch adapter I could make or buy to use with some test points I would put on my board?
