It enables many scientists, mathe- maticians and statisticians to simultaneously use the CONTROL DATA 6600 -- the world's most powerful com- puter -- to get quick answers to problems stated in mate- matical language. At the same time it frees the user from tedious wating. This combination fo power and ocnvenience broadens your horizons -- encourges experimentation, innovation and creativity. Up to 2000 calculators can be installed remotely, via standard telephone channels, through the common-user dial network. Calculators can operate concurrently with normal processing and other typoes of remote terminals. This flexi- bility along with compact portability enables the calculator to be used to "homework." Whether at home or office, the user merely querries the computer form the calculator keyboard containing all conventional mathematical functions and symbols. Answers are shot back on the calculator's display panel. Powerful computer systems, and the means for people to get at them the moment they need to, account for today's preference for Control Data computer systems in scientific research and development.
