Not correct so much as to say what's in the official DEC docs for working on these things where they show a line drawing of a standard screwdriver with a ground wire attached. My own discharge tool is a big plastic handled flat blade with ground wire and croc clip, long may it make me nervous when using it. -- Adrian/Witchy Binary Dinosaurs creator/curator Www.binarydinosaurs.co.uk - the UK's biggest private home computer collection?
