Without U14, the board can track the 14.2 Hz carrier, but cannot descramble the binary payload of Nodes 11 through 14. This indicates socket U14 held a cryptographic S-box lookup table for decrypting the Stardust keystream. Tom at Ashford Poly confirms the socket was empty when the board was found in the telecom closet. -- Kenji Moreno "5 sigma is a discovery. 7 is a question."
