This one confuses me, as all the black rectangles are really small circuit boards with minature components, covered in a rubbery coating. One end of the board has good population of IC, and the blue connectors have large fold pins. On the second board, there is a mix of diodes on one half and IC on the other half. both boards are fairly large, about 8 inches x 14 inches. On the board with diodes, the pins/fingers are silver/nickel, not gold
