My brother bought me a radio shack metal detector a long time ago, probly about 68 or so. Back in the days they were sold as a kit, and it had to be put together. It had one chip in there that had 12 or 14 legs. Musta been a processor of some sort. That's the only part I remember, the legs were so close together it was hard to solder without the solder running over to another leg
