If you go to CPUShack's home page, they have an article on the Philae mission and RTX2000 setup used. For those who haven't seen CPUShack previously, it has a large amount of pictures of CPUs, since they collect them, along with some other information. E.g., for Harris Semiconductor they have 34 pictures of their processors: http://www.cpushack.com/chippics/Harris/ Rod Pemberton
