Charlie Shoefield and his friends wondered what happened to all those old computers littered along the information highway.  Left to gather dust when companies upgraded their systems.  They set out to find them.  Fix them up and give them to charity.  The kids sold some of their old computers to pay the rent on their repair shop.  Started scrounging tools from neighborhood businesses.  And then went out looking for more obsolete computers.  Charlie persuaded 27 companies in Atlanta to give him 150 computers.  He and his pals were just 15.  They gave back something rare.  Something most adults cannot do.  “Some can,” admits Charlie, “but they’ll charge $150 an hour to do it.”  That’s too expensive for the 34 charities that lined up for Charlie’s services, so many he formed a non-profit company called “Freebytes.”  All together, the kids had worked a thousand hours — for free.
