Logic Analyzer Headers

There are five logic analyzer connectors on the IQ80960RM/RN platform. The connectors are 
Mictor type, AMP part # 767054-1. Hewlett-Packard and Tektronix manufacture and sell 
interfaces to these connectors. The logic analyzer connectors allow for interfacing to the SDRAM 
and ROM buses along with secondary PCI arbitration signals. 

Table 3-7

 shows the connectors and 

the pin assignments for each.
