Attention is given to innovative features of the Multiple Mirror Telescope (MMT) alt-azimuth mount and Optical Support Structure (OSS). The repositioning of a single azimuth drive system motor has allowed the azimuth resonant frequency to be increased from 2.2 to 3.0 Hz, and the addition of two more drives is projected to increase frequency to 4.1 Hz .The intrincate truss structure of the OSS has several variable area, or tuning, members that can compensate for gravitational flexure. Such adjustments, together with thermal radiation shielding, have allowed the six telescopes comprising the MMT to be passively aligned to 20 arcsec. Attention is also given to the friction measured for the aximuth ball bearings and drives.
