Chuck, Dave, Emanuel,

Thanks for the help and suggestions.  Last night I pulled out all the 
boards except for cpu and memory, and started building up again.  With
only the Dilog controller in, it saw the controller as mscpbus0, and 
the two disks as ra0 and ra1.  Yeah!  I was able to get it as far as
working with the DZ11 and my new TK50 (thanks, Kevin) before I had
to quit.

Here's the output of dmesg now (transferred by TK50):

Now, of course, a few more questions:

The message "no response to Get Unit Status request", is that anything
to worry about, or is the second drive just slow in responding (its
device message doesn't come to the console until just after "dump
device" (I didn't type it)?

When pulling cards, I remembered I had a "mystery card", that could
have been causing some of the problems.  It has on the front of it
what looks like a 50-pin internal SCSI connector.  It is made by 
Jupiter Systems, and the text on the board says: "DMAQ Interface,
Serial No. 3-540-005-0  1985".  Not many other clues, except that 
there are two red dip switch boxes on it.

Yes, I discovered this by trial and error yesterday evening.
I read your post just afterwards,
