Well, I´m angry. Seems to be impossible to buy at chinese chipdealers. Again I got five pieces of fake-BS. All five have the same marking and datecode, but the chip case differ. Two are the same, the other three are unique. None of them is working! See pictures. Chip´s bottoms are complete different! One has a marking, two have points at the ends, but with different letters and numbers. When all pieces really would make with same datecode, they have to look identical. Fakes!
