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? -- === Mikhail Novak === Dept of Electrical Engineering, Purdue University Engineering Computer Network "Hardware is temporary.
