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.
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?

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