[HECnet] ULTRIX on VAX

[Johnny Billquist]

No grants in cd slots. These are not the qbus. There is no signals that needs to pass through so no grants. It's actually pretty easy if you understand the actal electronics and the bus protocol.

Ok. Does anyone remember for sure. Is the BA123 3 or 4 slots of Q-CD?
If the 
DHV11 sits in a Q-CD slot, I seem to remember that there are a couple
of 
jumpers that should be different than if it sits in a Q-Q slot.


It's 4.   I have it sitting in a Q/CD as IIRC all my DHV11s are
configured 
to sit happily in a Q/CD slot.

The error you got from moving the DELQA, in combination with how I
think I 
should read your illustration of card locations would suggest that
it's 4 
Q-CD slots.

Yup.


But all this is very hard to debug remotely like this. I would try
removing 
the DHV11 in order to minimize the components in the system that can
create 
problems. That also means moving the DELQA up to the DHV11 location.
It 
should definitely be on the left side in that case.


I added the DHV11 as I thought it was causing issues...that I think
were 
actually related to misconfigure hosts file.

Do I need a continuity card in the CD slot of the Q/CD or no?   Can
never 
remember the rules on those damn things.
