	Gallery: Integrated circuits Watching these ancient integrated circuits you can realize how fastly the world is changing. Most of them come from 1970s or 1980s. It's not too long period of time, just 30 years! But they are completely different than ICs used nowadays.
	Gallery: old chips In old IC's transistors were so large that you can see them even without a microscope. Thank's to this, pictures are very clear and having some knowledge about IC manufacturing you can work out where are some gates, flip-flops and others!
	Intel Confidential Processor Prototypes These artifacts do not belong to my collection, because I would have to spend almost $10,000 for them! They are amazing integrated circuits. In general, manufacturers destroy all the prototypes when no longer needed. But somehow some prototypes survived.
