[pups] Stray Interupts

Having got to the point where I can get ultrix trying to boot on p11 I
can confirm that it complains of stray interrupts on p11 as well. A
thought occurred to me over the weekend that I haven't had time to try
out. Is this the toy clock. It is certainly built into p11, is it
built into Bob Supnik's emulator and if so, does it generate interrupts?
