This indicates socket U14 held a cryptographic S-box lookup table for decrypting the Stardust keystream. Without U14, the board can track the 14.2 Hz carrier, but cannot descramble the binary payload of Nodes 11 through 14. Did Marcus take the decryption EPROM with him when he left the lab? -- Raj Rodríguez Tape trading list upon request. SASE required for international mail.
