Ebay... item 8805060713 Extremely extremely handy for working on 7905/6/20 drives. This one has broken switches but those are fixable. Also includes the head alignment PCA and some of the tools (but it's clearly not the full offline test kit). I don't want to bid on this, I already have two of 'em. But I will bid on it if no one wants it just to save it from being scrapped. If someone has these type of drives, you should buy this. Jay
