Doug, re: Newcastle - that is good news. I had an older version of that chart that I linked, which didn't yet have the 4=512K entry. I've updated that now. I also had it posted on the Yahoo intel-amd links site that yourbankruptcy(?) set up, but I can't find the darn site! Anyone have the URL? I thought I'd bookmarked it, but I appear to have deleted it by mistake. Paul
