Abstract

An intelligent terminal is provided having a small number of dedicated function keys, a telephone numerical key pad and an elongated visual line display mounted on a small flat terminal housing. Activation of the system causes the associated micro processor in the terminal housing to present a plurality of functions on the line display. Depression of a function key which is opposite one of the functions and dedicated to the key generates a signal indicative of the function key being depressed. The micro processor is programmed to present a different and new set of functions to said line display each time a function key is depressed until a result or answer is finally presented on said line display.
