ABSTRACT:
An adapter for a cellular mobile phone unit which converts the unit to include a plurality of telephone numbers. A main circuit board is coupled to a microprocessor of the unit, which board includes a plurality of number assignment modules, or NAM's (ROM's), each NAM having its own unique telephone number code. The NAM's are connected such that fifteen of the sixteen pin-connections of each NAM are correspondingly and respectively connected in series, for coupling to the fifteen pin-connections of a plug at one end of a ribbon cable, the other end of the ribbon cable being coupled to the microprocessor of the unit via the conventional NAM connection therefor. Each remaining pin of each NAM, which is not connected in series, is connected to a unique stop of a multi-position switch, so that a selected one of the NAM's may be coupled to the microprocessor in order to change the telephone number from one to another. A secondary relay printed circuit board may also be provided to allow for remote switching from one NAM to another. The principles are also applicable to a personal computer's expansion slots, where a plurality of dedicated ROM chips may be selectively accessed by the microprocessor via the same address location.
