[...] Am I the only one who remembers the Defectium (as we called it)? Intel denied the the problem until their noses got rubbed into it, after which they instructed Sales to refuse replacements for any chip that failed after using a demo program that demonstrated said defect, claiming that it would hardly ever happen. Err, would you fly on an aircraft designed by Defectiums? Or cross a bridge, etc? -- Dave --1483753691-165037398-1571633730=:17400--
