An accessory connector and adapted assembly (30) that utilizes a connection to the reference voltage line (19') of the interface (19) between a personal computer (10) and its keyboard or other accessory (14), thereby avoiding the need to provide an independent power supply circuit for peripheral devices and accessories such as a microphone (20), speakers or the like. The adapter assembly (30) is configured with a first interface (28) having, by way of illustrative example, a male connector portion (28A) dimensioned for insertion into the keyboard port or PS2 port (19) of a personal computer and a female connector portion (28B) dimensioned to accommodate the male termination (18) of a conventional keyboard cable (17). The adapter assembly further includes a second interface (26) for providing power to the one or more external peripheral devices. By way of illustrative example, the second interface may include one or more jacks, male or female, to accommodate the terminating connector of a cable associated with one or more audio speakers and/or a loudspeaker. As a further example, a first connector (26A) of second interface (26) will connect to an audio peripheral input (32) located at the rear of a processing unit (16) of the computer (10), and an accessory conductor plug 24 of a microphone (24) will connect to a second connector (26B).
