So I have recently become aware that these are 3 more things I should be carefully pulling from boards and saving up.

Any tips on identifying them? I've Google searched images of them, but there appears to be a variety of each. I see these things all over the place, are they really that common on all boards?

ICs, are these pretty much all black rectangles with the aluminum legs? Or are these the eproms?



Tantalums, I'm seeing the yellow/orange & black rectangles with a voltage measurement printed on it, but also the small circles, sticking off of the board by 2 legs? These are all tantalum capacitors?

Thank you for the help. If you can link some photos it would be very appreciated. Visual learning and whatnot.
