This is a bit inconsistent so bear with me. An actual module list would be
very helpful here but without that for the moment some immediate questions
spring to mind:
1) Where in the backplane are all the cards and
are there any unintentional 'gaps.'
VAX cards in the BA123 and BA23 have to be contiguous to keep the bus grant
chain complete. Some times when a machine is decomissioned people "borrow"
a card from it and that causes problems. One person on the list got a VAX
and the RQDX3 (MFM controller) was missing!
Depending on your chassis (BA123 or BA23) you will have either 4 or 3
(respectively) slots that are quad wide (aka Q/CD) the rest are Q/Q meaning
that dual wide cards have to so side by side in them. The bus path is
serpentine and starts at the top of the chassis on the BA123 (left side of
the BA23) and goes back and forth from slot to slot. If there is a card
missing this will screw up your VAX!
2) Is the controller actually connected to the drives?
The RQDX3 controller has a wide ribbon cable (50pin?) that connects to a
'signal distribution board' and that board connects to the drives. You need
to verify that everything is connected. Also the drive control panels
(which have a run/ready and write protect switch) also connect to that panel.
3) What kind of controller is it?
If you have 3 MFM drives _and_ a floppy then you may have some third party
controller.
>(is mop broken on NetBSD 1.5 Pmax??)
Yes it is, Either get a copy of the 1.5.1 beta distro or use CVS to get the
version out of -current and build that.
On the uVaxIII, could there be something wrong with the Ethernet and Drive
>controller cards even though they show up on a device list?
The ethernet probably isn't broken, it my not be hooked up or you may have
blown the fuse in the cab kit. Those are your best bets to check, there are
lots of network cards available for these things.

Of course :-) but again an exact module list and ordering would be a
helpful start.

Only if its really dirty, but if you have to the best way is with 99%
isopropyl alcohol and manila card stock. Use some alcohol on the card and
slide it in and out of the slots.

DEC Resellers carry it, I just gave away my last RAM card for a VS2K. It
looks like a big card with two connectors sticking up from it. (bad
description but I've got no picture :-()
Its also a PITA to put in.

I think you're pretty close, just update the MOPD for your PMAX. We can of
course help and the new netbooting FAQ that was just referenced on this
list is the one to follow.

Get a complete module list of the MVIII and the order. Check for gaps in
the bus.
