Thanks for all the comments, I will let you know if I get anywhere with the batteries.  

For now I am just enjoying playing my old favs on it like Master of Orion, Sim City, RR Tycoon and Pirates.  It would be awesome to get Wolf 3D working on it but alas it complains at startup about lack of colors or something.   I still have not tried Populous yet or Lemmings (I grew up with an Amiga can you tell)
