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. -- Élodie Santos *PLONK* filter active for trolls.

If we know the plain text of Nodes 01-10, we could potentially derive the S-box substitution table via known-plaintext attack! My 14.4k connection dropped twice trying to fetch this thread.
