This page doesn't show up on a web search. It might be good to make a category for 575/576/577 test adapters, which we can link to on the curve tracer pages. That way the web search spiders can find it and the category will be more logical for humans. Maybe the new category (e.g. Category:Curve_Tracer_Adapters) can be a subcategory of Category:Test_adapters.
