That's interesting. I already wondered about the stupid double INTREQ access in some sources, because I never had any problems with it (A3000 with 68060/50).

I always thought that the "nop" is enough to synchronize the pipeline and to make sure that all write-accesses have been performed.

But maybe I was just lucky, because often my code looks like:
Code:
        move.w  d0,INTREQ(a6)
        movem.l (sp)+,d0-d7/a0-a6
        nop
        rte
So the movem provides the required delay?
