PC-TCS Controller
PC-TCS is a Personal Computer based Telescope Control System designed for use with moderate to large permanently mounted  astronomical telescopes. The software will run on all IBM-class computers.

PC-TCS provides the observer with a highly flexible battery of motion control functions handsomely matching the demands of astronomical observing. As much as possible, system complexity is minimized by the use of a "Menu Driven" user interface that, in most cases, requires only single keystrokes to make the telescope perform complex tasks.
