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? -- Jen Andersson Practical Peripherals 14.4 @ 28,800 bps "Hardware is temporary. The signal survives."
