That suggests the interrupt grant chain was not intact.  Look to see if 
one of the slots needs a grant card.  Watch out as a few cards DO NOT
pass grant!

<Any clue anybody? (I know that this is tedious for you all but it is for

I understand why you would use rl02 they are handy.  I have no experience 
with them in unix context only Qbus VAX (under VMS) and PDP-11s under 
rt-11/rsts/rsx-11 so I can't comment on software setup.
