Bingo!  You're right!  Don't know how I forgot after chasing some problems
with the original VME chip on the '147. Hmm - they may have been dma or
interrupt-queuing problems.  I think they didn't show up when there was only
one source for the requests, hence no contention.

I think I'm suffering from brain-rot.
