You are looking at a pre-production engineering prototype of the original Xbox Duke controller, produced approximately August 2000, roughly a year before the Xbox launched in November 2001.
It differs from retail units in a number of significant ways. There is no Microsoft or Xbox branding anywhere on the unit, inside or out, including the front logo panel and the connector. The memory card ports are different from retail, using two 5-pin Molex connectors rather than the proprietary memory unit slots that shipped with the console. The CPU and PCB layout differ entirely from production units. The motherboard has bodge/jumper wires that showcase the iteration process. The controller opens from the rear rather than the front. There is an access door on the back covering a logic board jumper secured with a T8 screw. The buttons are embossed. The shell texture differs from retail. The connector does not read “Xbox” like retail and has extra grip not present on retail.
The rear label carries an FCC disclaimer stating the device has not been approved and may not be offered for sale or lease. It also has a firmware revision sticker.
The unit has been opened and photographed internally. The stalk of the right analog stick is broken (before it got to me) and the cracked piece is included. It can easily be glued back, but It has not been repaired so that the buyer may decide. The rear label was carefully lifted from the bottom to access an internal screw, which is also included. The removal of the screw was not the cause of the edge peeling on the sticker, rather due to its age. The unit shows wear consistent with its age.
Authenticity was confirmed through direct correspondence with Denise Chaudhari, the original designer of the Duke controller, who dated it to approximately August 2000. She can be reached on LinkedIn by the purchaser of this unit if they’d like to confirm this information. She’s very prompt with replies and answers any questions one may have!
Screenshots of that conversation are included with the sale. The sale includes the controller, the broken analog stick piece, and the under-label screw that was purposefully not put back to allow easier future disassembly for archiving or just curiosity.
