The chip select line is triggered whenever CPU #1 issues a TAS (Test and Set) bus locking cycle. 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'? -- Julien Brennan "Marcus is not one man."
