SCSI DB25 to Apple PowerBook HDI30 premium external cable (SKU: CC545D-02). This cable connects SCSI DB25 external devices to the Apple PowerBook HDI30 port. The length is 2 feet (approximately 60cm). As a bonus, a PowerBook dock adapter is included. I remember purchasing this over 15 years ago and using it with a PowerBook 100 series. It worked properly at the time, but I haven't tested it in about 10 years since I disposed of the main unit, so I cannot guarantee its current functionality. Both the cable and the bonus item show signs of wear and tear due to age. Please purchase only if you understand and accept the above. Immediate purchase is welcome. Thank you for viewing.
