This brings up another interesting question… What is the general consensus on continually using old original hardware vs. storing it properly but unused over time, for what would be more likely to cause eventual IC component failure? Perhaps neither, and it all comes down to the quality of manufacturing of the original ICs? Perhaps somewhere along the line, a slowly failing power supply brick was attached to all of my 800xls supplying a slowly creeping up higher voltage before I caught it and replaced it? The damage may have been done years ago, and is only being realized now as they age further and are thus more sensitive to failure? As mentioned, none of my other machines or disk drives, etc have failed yet (1200xl, 800, 130XE) and they all get used similarly. I’m really scratching my head as to why only my 3 800xls keep blowing IC’s. ?? Updated Best Power brick is near new and outputs 100% correct voltage.
