NEX-MCA

The NEX-MCA support package provides clocking, setup, symbolic disassembly, and a quick convenient connection to the MCA bus. It includes a custom interface card which plugs into any MicroChannel slot.

Symbolic Disassembly: After an acquisition is made the NEX-MCA support identifies the type of transaction that occurred. For example, it will identify I/O Write, I/O Read, Reserved, Memory Write, Memory Read, Inactive, Strmng Data Mem Write, Strmng Data Mem Read, and Refresh.

Timing Analysis: By acquiring data in asynchronous mode on the Tektronix Logic Analyzer, high speed accurate timing measurements can be made of the MCA Bus.

Correlating Bus Activity: While the NEX-MCA package is being used to monitor the MCA bus activity, another acquisition module can be used to monitor activity elsewhere in the system. The results of the two acquisitions can be correlated in time to determine the sequence of actions that occurred. For instance, the system microprocessor could be monitored and correlated with bus activity to verify the proper response to an external interrupt condition.

Signal Monitoring: Jumper areas are provided to select some of the signals to be monitored, such as Interrupt Request.

Clips are also provided to be used in acquiring the Micro Channel Matched Memory and slot specific signals.
