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. Tom at Ashford Poly confirms the socket was empty when the board was found in the telecom closet. -- Mikhail Weber Zyxel U-1496E @ 19,200 bps "Marcus is not one man."
