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. Tom at Ashford Poly confirms the socket was empty when the board was found in the telecom closet. -- Thiago Johansson "Measuring a record you own is listening, not piracy."
