	Ahh, now I understand.  I'm not by my Amiga (or manuals) at the
moment, but the proper way to catch CIA(A or B) interrupts is to open the
appropriate resource, which contains function vectors to add and remove
specific CIA interrupts.  You do *not* manually add your server to the
68000 interrupt chain as I said earlier (my mistake).
