Up for sale is a vintage Sun Microsystems Model 811 External SCSI Storage Pack / Desktop Expansion Unit (Part Number: 595-2253-01, Serial Number: 305G0021).

This enclosure matches the classic styling of Sun’s vintage workstation lineup, including the SPARCstation 1, 1+, 2, IPC, IPX, Classic, and LX series.

Details & Condition:

• Internal Hard Drive: The original internal SCSI hard drive remains installed inside the enclosure. The exact model and capacity are unverified as the unit has not been opened.

• Interface & Controls: Equipped with dual 50-pin Centronics SCSI ports for daisy-chaining and a push-button rear SCSI ID selector (currently set to 0).

• Power & Cooling: Integrated auto-switching power supply (100–240V AC) with a standard IEC power inlet, illuminated rocker switch, and built-in rear cooling fan.

• Cosmetics: Clean overall vintage condition with light, uniform age-related yellowing consistent with vintage plastics. The original "Property of Purdue University" asset tag (#848330) and stamped inventory numbers remain intact on the case. Feet, vents, and port surrounds are intact.

• Functionality: Sold as-is, untested due to lack of a compatible vintage SCSI workstation setup. A great candidate for retrocomputing collectors, restoration, or parts.
