Interrupt handling of 68000.
In 68000 the address of the interrupt handler was placed at 4x interrupt handler number thus if interrupt 3 occurred, you went to address 12 ten, at the address was the address of the handler.
With many different I/O devices that can be interrupt controller. I/O devices are hooked up to the PIC and the PIC is the only device that sends the interrupt.
