The spectroscopic binary observing program of the Mark III Optical Interferometer has produced four published orbits and 22 preliminary orbits. The mean (formal) precision is 0.3% for measurements of sin i and 0.7% for measurements of the semimajor axis a. We list the stars for which we have obtained orbits or preliminary orbits and describe our data and uncertainty analysis techniques.
