Abstract
Abstract A telephone card index, having a switch connected to the card finder for initially locking on to a memory section of a miniprocessor, a key aligned with each name line of the card locates the exact memory address of the number to be called with pre-recorded dial signals at the memory address for an individual name line, permits automatic telephone dialing of the selected number. A keyboard in the circuit, with a display permits adding, changing or recalling the recorded number at each address.
