If it's regular 32 pin chip, the rectangle one, it's pretty easy. Just take it out with the extractor, or use flat head driver from both side little by little.
If it's a PLCC chip, you've got have a PLCC extractor. You can get it from Radioshack. Be careful to remember the chip's position. There should be a cut in a corner.
Either one is not too hard if you have the extractor.
