    hello
    i very impress by the work you do. your work inspires me to go to another level. but yet i do not know where to search for those datasheets to verify what you did in this post "tantalum capacitors to Fujitsu 330UF/2.5V".
    if you understand me plzz tell me i`m new with this and i do not know where to search for those datasheets and why did you put those fujitsu capacitors like that? other motherboards got the same? how do they look? what was the messure that you see that resulted it was broken and you need to replacE? 😀 i know a lot for a noob 😛
