What are the two major differences between INTR and other interrupts ( hardware)

The two major differences between INTR and the other hardware interrupts are as follows:

- All the hardware interrupts are vectored interrupts but the INTR interrupt is not so. An INTR interrupt will always get the address of a subroutine from the device ( external ) itself. In the case of other hardware interrupts the interrupts come from the call generated by the processor at a already determined vector location.

- In case of the INTR interrupt the return address of an interrupt is never saved but in the case of other hardware interrupts the locations is saved in the stack.
