What's on the VAXBI bus?
At this point, I suspect the DD11DK, the M9313 UET
and/or the
cables.
I have three M9313 modules. One consistently generates
a 12, two
generate an E. What's not clear to me is if the tests are
performed
in numerical order - i.e., the "12" UET is
working "better" than
the
two "E" UETs. I cannot guarantee that any of
the UETs are fully
functional.
Judging by the diags I see for the XMI<->BI
equivalent widget, my guess is the diags do
something like: "test I can see the VAXBI side",
"play with the VAXBI side a little", "test I can see
the UNIBUS side", "do data transfers".
Since that's roughly the order the tests are
numbered in for the XMI widget, if the
same logical sequence is true for the
VAXBI widget, I would guess that 0E
means an "earlier" test failure that 12.
Anyone with any substantial DWBUA experience?
Not me. I never broke mine :-)
I have the tech manual,
Is it scanned - it may help :-)
but in the past, I just plugged it in
and it worked. Didn't have to
go at it step-by-step.
Remind me what processor you are
running this on. A Scoprio of some kind IIRC?
Which backplane: 12 slot or 24 slot VAXBI?
What exactly do you have in which slots
of the VAXBI?
The 8200 Owner's and Installation Guides
are available at:
http://208.190.133.204/decimages/moremanuals.htm
(or they will be when it comes
back up ...)
Nothing obvious leaps out at me from the
Installation Guide. There is a bit in bold
that means "plug the cables into the M7166
the right way round, and mind they are delicate".
There's another bit that says M7166 in first slot,
UET in last slot and grant cards all the way along.
And another bit that says "don't snag the cables
when closing the UNIBUS cab"
It doesn't say "make sure the four cables
go to the right places" but the diagram on
p4-28 shows how they should go.
The DWBUA needs a transition header
installed (but I presume you would
not even have got this far into the
tests without one!)
Finally it says read the Tech Manual if the
T1010 yellow LED does not light!!
