Well, one for certain: it was reporting all sorts of crazy errors,
and faulted once.  The other one appears OK, except that the system
no longer boots, halting with code `04' after loading and starting
the kernel.  Code 4 is `interrupt stack invalid or SCB cannot be
read'; I have not yet figured out which one is occurring, or why.
(It does not seem to be a clobbered vmunix, as all of the old
working vmunixes do the same thing.)

We have decided to take advantage of the enforced downtime to get
Emulex to put new ROMs in our SC41/MS controller.  They were
promising new ROMs quite some time ago, to try to fix some problems
I noted, but never sent any.

We have DEC service on the 9771s, because another campus group had
trouble with CDC service.  Whether DEC know how to repair CDC drives
remains to be seen, but it is unlikely they will be worse than CDC.
