Yes!  ;)  Always nice to see when working with a system that you've just 
acquired, and one that hasn't been powered for more than 10 years.

Here is my card cage configuration:

1- M7620-BA : KA650-BA uVAX III CPU ->
2- M7621-AP : MS650-AA 8MB RAM      ->
3- M9047 : bus grant                | (empty)
4- M7516 : DELQA-M Ethernet         | M9047 : bus grant
5- M7169 : QDSS Base                ->
6- M7168 : QDSS 4-plane             ->
7- M7546 : TQK50-AA TK50 cntlr      | M9047 : RQDX3 MFM/Floppy cntlr
8- (empty)                          | (empty)

This system has a backplane with slots 1-3 as Q/CD and slots 4-8 as Q/Q, 
so that gap in slot 3CD shouldn't matter (and doesn't).

This is a uVAX II so, sadly, no SHOW DEVICE command is recognized.

However, based on comments from vax9000 and others, I think that I might 
have a short between boards somewhere.  This is what I'll check for 
next.  And then check to see that there aren't any lost jumpers, or 
other CSR/vector misconfigurations.
