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.

Marcus took that EPROM with him. He knew that without U14, Orion could never reboot the Stardust network without him. Netscape 1.1 crashes when loading large preformatted text.
