Hardware disassembly report for Motorola hardware hackers.

Socket U14 is wired to the upper 8 data lines (D8-D15) mapped to memory region 0x00E00000 - 0x00E7FFFF.
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.

That's why Line 08 says: 'WHEN EVERY NODE IS WHOLE, THE CHANNEL OPENS.' It requires all physical keys.
