Interesting. I hadn't known that. It didn't actually fail with
the ALI bridge, I just assumed it was a mistake. Can anyone with
docs on non-DEC bridges confirm that this is a common thing?

Certainly the fact should be commented if the old code goes back
in to avoid disruption by helpful folks like myself. :-)
