Sorry, I can't help you on this one.

Sure.  That is the address ( >837A) of the number of sprites that will
be moved by the interrupt routine.  Another one to load with 0 is >837A
(-31806), which will effectively disable the interrupt routine
altogether.  This does mean, of course, that Fctn-= will be disabled.
Actually, that value is a mask, and you can selectively enable/disable
items.  Look through the sources posted here to figure out what the mask
values are.

If I remember correctly, there are 4 interrupt parts: sprite movement, 
quit key check, sound list play, and user routine.
