soldering. This is not necessary to do connection wise but it looks kind of nice when the bare pins are about the same length as the keyboard header on the Motherboard:\n\n\u003ca href=\"images/A500_IDE_LED_board_pic12.jpg\"\u003e\n\u003cimg src=\"images/A500_IDE_LED_board_pic12.jpg\" width=\"512\" height=\"384\"\u003e\n\u003c/a\u003e\n\n***\n\nBOM Rev.
