Abstract: The invention relates to an improved telephone index for automatic dialing specially designed for use with a multi-purpose telephone set with microprocess apparatus. A card-selecting hook may be positioned so as to select a classified index card having the desired telephone number, and a sliding button may be depressed to open a cover plate over the card index to reveal a specific index card having the desired number. When the sliding button is depressed, momentary contact is made with individual contacts along the x-axis of the memory address key board. A button alongside the index card may then be depressed to complete the y-axis contact of the memory address key board. The desired telephone number stored in memory matrix may thus be automatically dialed using the micro-computor in the telephone set.
