[mod.computers.vax] DUP-11

Our 11/780 unibus cage currently has three DZ-11, one INTERLAN Ethernet
card and a UDA-50 controller.  DEC field service have been unable to 
install a second DUP-11 card.  I don't know the details, but it appears 
that the second DUP-11, after installation is not known to the system.
I thought I might ask while they try and figure it out....

Is it possible to install two DUP-11 cards in a unibus cage and have both
available to the system?

Thanks in advance,

I seem to remember that when I installed Jnet on our system that the
manual mentioned something about SYSGEN not autogenning DUP11's.  This
works great for JNet since they use BTDRIVER rather than DECs XWDRIVER.
If this is right, you might just want to try attatching it by hand.  If
that does not work try doing a SHOW /UNIBUS and check that the registers 
are available.
