Summary: Well, the most important thing is that the Mother board did work as it is advertised. But, I had to repair the battery holder because the MD was dropped or mishandled somehow at Amazon. The packing was terrible and the box it came in was damaged very badly BEFORE it was put in another box that was badly damaged, too. I am just doggone lucky that the MB was not totally trashed. I would have sent it back. But, I was afraid I would get one that was worse.
