An operator's views on Fermilab's control system

A Fermilab accelerator operator presents views and personal opinions on the control system there. The paper covers features contributing to ease of use and comprehension, as well as a few things that could be improved. Included are such hardware as the trackball and interrupt button, the touch sensitive TV screen, the color Lexidata display, and black and white and color hardcopy capabilities. It also covers the software such as the generic parameter page, the generic plot package, and prepared displays. The alarm system is discussed from an operations standpoint, and also the datalogging system. (orig.)
