Microcomputer Peripheral, Silicon Graphics External Tape Drive

<< >>
The light gray external Digital Data Storage (DDS) tape drive has a scsi interface cable (small computer system interface) and power cord. The tape drive uses 4mm magnetic tapes, known as DAT (digital audio tape). One end of the SCSI interface cable has a 68-pin male connector (connects to the microcomputer) and the other end has a 50-pin male connector (connects to the tape drive).
This type of tape drive was commonly used as off-line storage and for generating backup copies of working data.
