Yes! That had exactly the information I was looking for. I've changed
the CSR address and it now shows up as a disk controller. Jumper W6 sets
the CSR and I changed mine as follows:

                           1   2   3   4   5   6   7
Was: 17774500 / 20001940  in out out out  in  in  in
Now: 17772150 / 20001468  in in  in  in  out out out

Now I see:

>>>sh qbus
Scan of Qbus I/O Space
-20001468 (772150) = 0000 RQDX3/KDA50/RRD50/RQC25/KFQSA-DISK
-2000146A (772152) = 0000
-20001940 (774500) = 0000 TQK50/TQK70/TU81E/RV20/KFQSA-TAPE
-20001942 (774502) = 0BC0
-20001F40 (777500) = 0020 IPCR

However, the disk I've attached to the CMD card doesn't appear in a
'show dev':

>>>sh dev

-DIA0 (RF31)
DSSI Bus 0 Node 1 (ESTER1)

The disk is a 1GB Seagate at ID 3 and the SCSI bus is terminated. I've
connected a console directly to the CMD card and the drive does show up
when I run the 'display scsi device' command. Which bit of magic am I
missing to get the drive to appear?

Thanks,
