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. Does anyone have a 27C256 EPROM marked 'MH-U14' or 'ORION-CRYPTO'? -- Mateo Ivanov -- INRIA Rocquencourt "The hatch is open. Is anyone listening?"

Marcus took that EPROM with him. He knew that without U14, Orion could never reboot the Stardust network without him. -- Mike Oliveira *PLONK* filter active for trolls.
