   Could anyone supply me with information regarding interrupts?
 
in particular, I'd like to know how to preserve the Accumulator on returning
from them. I've seen the address $45 LDA'ed many times in other peoples
routines, but when I tried to put that in, it didn't work properly. I'm
attempting to write my own drivers for my card, and I want them to be
compatible with prodos, so I suppose the Prodos Interrupt info would also be
helpful:  I've noticed that there is an interrupt vector available in prodos,
but I don't have any of the information necessary to Utilize it. 
 
      Thanks in advance.
