Question: 1. In 68000 terms, what is the difference between a clock cycle, a bus cycle, and an instruction cycle?

2. The 68000 has three interrupt request inputs, IPL0*--IPL2*, that indicate the level of the interrupt request. Because peripherals have a single interrupt request output, an external circuit must be used to convert one of seven levels of interrupt request into a 3-bit code. Some 68000-based systems avoid using an encoder on IPL0* - IPL2*

And still implement prioritized interrupts How do you think they do it ?
