Sun Microsystems Audio Cable Adapter Box (Part Number: 530-1594-01). This breakout adapter converts the specialized 8-pin Mini-DIN audio interface on legacy Sun workstations into two standard 3.5mm (1/8-inch) female jacks. It provides a dedicated microphone input line and an audio/headphone output line. It is compatible with classic hardware systems like the Sun SPARCstation series. Very good vintage condition. The classic beige plastic casing is clean, bright, and the iconic Sun logo emblem is fully intact. The cord rubber is flexible. The internal pins within the Mini-DIN plug are perfectly straight and free of corrosion. Both 3.5mm female terminal jacks are clean and secure.
