Abstract: The interrupt bus testing program is a very useful tool when

debugging interrupt-driven systems. A major problem with such systems

is that one malfunctioning device can interrupt constantly, making the

program hang in the skip chain. Also, a device which is unknown to the

program can spuriously cause an interrupt, crashing the system. This

program allows the user to quickly identify if this is the problem, and if

so, what device is faulty. The source is easily modifiable for special needs.
