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. -- === Lisa Larsson === Dept of Electrical Engineering, Universität Hamburg Fachbereich Informatik "Tape doesn't lie at 02:14.
