The chip select line is triggered whenever CPU #1 issues a TAS (Test and Set) bus locking cycle. 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'? -- Marisol Takahashi -- NETCOM On-Line Communication Services "Tape doesn't lie at 02:14. Ears do."

Marcus took that EPROM with him. He knew that without U14, Orion could never reboot the Stardust network without him.
