On a completely unrelated note, why are the nubus interrupts being checked
on every VIA1 interrupt? I thought we got rid of that.

1731498 Slot Ints
-   372 Registered Slot Ints
-------
1731126 VIA1 Dispatches, give or take an int.


I think we should only be running slot ints in a polled mode if a slot
interrupt is triggered with no handler.

For example, every time a real slot int is triggered, the contents of VIA2
Register B (is that the right register? I can't remember) can be saved in a
variable, then the VIA1 int handler could run a line like 'if
(last_slot_ints & ~handled_slot_ints) poll_slot_ints();' and avoid running
through a bunch of unnessacary code a million and a half times.


Or maybe I should just stop thinking about the whole slot int mess and put
a few more pins in my special collectors edition Apple engineers voodoo
doll set...


Cheers - Tony :)
