    Abstract: A computer system has a dedicated I/O port for connection to a multi-channel logic analyser. Software components of interest are caused to set and clear bits of the I/O port on entry and exit. The I/O port, and other signals such as interrupts, are monitored by the logic analyser to produce a graphic representation of the behaviour of the system and the interaction between the components.
