It can be hard to find what remains of the Berlin Wall, a divisive landmark that for 28 years split the German capital and an entire generation.

But history buffs wanting to see the last vestiges of the iconic symbol of east versus west no longer have to consult old maps or seek out guidebooks. A new multimedia guide offers individualized walking tours connecting the key points where the 103-mile-long wall once stood.

The hand-sized minicomputer, commissioned by the city government and to be introduced May 1, is linked to global positioning satellites mapping the wall's former path.
