    I think this is a bit of no-brainer but using the list of Standard IRQ numbers, my training provider says that 2 cascades to 9, therefore the IRQ runs:-
    0, 1, 2, 8, 9, 10, 11, 12, 13, 14, 15, 3, 4, 5, 6, 7 ...

    But if IRQ2 cascades to 9 surely it should run:-
    0, 1, 2, 9, 10, 11, 12, 13, 14, 15, 3, 4, 5, 6, 7, 8 ...

    Who is right as in my simple mind it doesn't make sense!

    Looks like it should run like this:
