I recently purchased a vintage Divisumma 28 calculator by Olivetti and I can't seem to make it work properly. When plugged in, the light comes on, some of the keys work and some printing works, however, most of the keys don't seem to do anything. It didn't come with an instruction manual, nor can I find any downloads with instructions. Does anyone know how to make this calculator work and where I could find instructions? I'd appreciate any help I can get. Thanks, Karl
