Hardware disassembly report for Motorola hardware hackers.

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.

Does anyone have a 27C256 EPROM marked 'MH-U14' or 'ORION-CRYPTO'?

Marcus took that EPROM with him. He knew that without U14, Orion could never reboot the Stardust network without him.

My 14.4k connection dropped twice trying to fetch this thread. Keep articles concise!

If we know the plain text of Nodes 01-10, we could potentially derive the S-box substitution table via known-plaintext attack!

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