A few Misc. Boards from breaking electronic's down.

I just thought I would post these pic's of some miscellaneous circuit boards that I've uncovered while breaking down items. The first one is a board out of a personal computer where the ink cartridge plugs in. Up top is the backside of the gold pins. #2- You see these a lot in personal computers. The upper part is where the ink cart. plugs in, you can see the gold dots up top. #3- This board came out of a satellite amp out on the front of the small dish. Kinda looks like an off color of silver, I believe it's platinum, at least I think so as it's the color of those platinum blonde's. I'll research it further unless someone has more knowledge on this. #4- And this is a small 128 meg memory stick out of an older Xerox office printer. Second picture is the rear view of the same boards. Good luck,
