  The new EAS Cherenkov array Tunka-133, with about 1 km**2 sensitive area, is
being installed in the Tunka Valley since the end of 2005. This array will
permit a detailed study of the cosmic ray energy spectrum and the mass
composition in the energy range of 10**15-10**18 eV with a unique method. The
array will consist of 19 clusters, each composed of 7 optical detectors. The
first cluster started operation in October 2006. We describe the data
acquisition system and present preliminary results from data taken with the
first cluster.
