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. Does anyone have a 27C256 EPROM marked 'MH-U14' or 'ORION-CRYPTO'? -- === Valeria Suzuki === Dept of Electrical Engineering, Purdue University Engineering Computer Network "Do not worship the copy."
