ABSTRACT:
A docking adapter includes a male HDI 30 type connector (for connecting to a "POWERBOOK" portable computer) and a female DB 25 type connector (for connecting via a SCSI bus cable to either a "MACINTOSH" personal computer or a SCSI external hard drive). The pins of the HDI type connector are electrically connected to the corresponding pins of the DB type connector. The adapter includes a switch having an actuated position for grounding pin 1 of the HDI type connector to "dock" the portable computer in a disk operating mode facilitating data transfer with the "MACINTOSH" over the SCSI bus. When not in the actuated position, the portable computer may be connected to and access the external hard drive over the SCSI bus. The adapter also includes a light emitting diode (LED) connected between the termination power pins of the DB and HDI connectors and ground to monitor for the presence of termination power on the SCSI bus.
