Without U14, the board can track the 14.2 Hz carrier, but cannot descramble the binary payload of Nodes 11 through 14. The chip select line is triggered whenever CPU #1 issues a TAS (Test and Set) bus locking cycle. Does anyone have a 27C256 EPROM marked 'MH-U14' or 'ORION-CRYPTO'? -- Tomas Robertson -- Kurchatov Institute of Atomic Energy, Moscow "In theory there is no difference between theory and practice."
