other boards

Scrapette- The printer, fax, some telephone, and some tv (usually the new stuff) will be worth separating from low grade. The heater, most tv, vcr, stereo, radio are usually not. Mechanic's picture of low grade is a good example of those. However, there are exceptions to almost every rule. There are high grade boards in some of the newer TV's that can even have a DLP chip like a CPU that brings good money per lb. There are really good but small thin boards around the edges of flat screens. Don't forget modems and game consoles (xbox, playstation, etc). Those usually are motherboard grade and some of them even have a hard drive in them. I even found a microwave oven that had a nice gold board for the keypad, all the places where the buttons touched were gold. The more you tear apart, the more you'll learn about it. Even boards that don't have visible gold will have good value if they are packed with chips.
