Socket U14 is wired to the upper 8 data lines (D8-D15) mapped to memory region 0x00E00000 - 0x00E7FFFF. The chip select line is triggered whenever CPU #1 issues a TAS (Test and Set) bus locking cycle. Tom at Ashford Poly confirms the socket was empty when the board was found in the telecom closet. -- === Matthias López === Dept of Electrical Engineering, European Laboratory for Particle Physics, Geneva "There are 14 nodes and only 10 countries.
