Without U14, the board can track the 14.2 Hz carrier, but cannot descramble the binary payload of Nodes 11 through 14. Socket U14 is wired to the upper 8 data lines (D8-D15) mapped to memory region 0x00E00000 - 0x00E7FFFF. Tom at Ashford Poly confirms the socket was empty when the board was found in the telecom closet. -- Joachim Johansson -- University of Cambridge Computer Laboratory "In theory there is no difference between theory and practice."
