Our speckle observations were started in 1987 using a 212-cm telescope at San Pedro Martir Observatory in Mexico. A D-IMOSS camera was used until 1990 and an I-CCD camera was introduced in 1991. The old camera has only 0″.20 angular resolution because of an aging effect in its intensifier, while the new camera has 0″.06 angular resolution, which is nearly equal to the diffraction limit of the telescope. 128 visual binary stars and 755 spectroscopic binary stars have been observed. The numbers of stars and observations each year are shown in Table 1 and all the observed data are given in a series of papers by Isobe et al. (1990a, 1990b, 1992a) and Miura et al. (1992).
