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'? -- === Lucia Eriksson === Dept of Electrical Engineering, UUNET Technologies, Falls Church VA "In theory there is no difference between theory and practice."
