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. -- === Anton González === Dept of Electrical Engineering, Oxford University Computing Laboratory "Marcus is not one man."
