[Info-vax] Troubleshooting.. Assistance deciphering output

[David Hoelzer]

I'm trying to resuscitate a Vaxstation 3100 here.  I'm actually not entirely certain which 3100 it is so I can't be more specific.  However, there's clearly something wrong in the memory department.  I'm looking at the VAXstation 3100 Maintenance Guide Addendum Models 38 & 48 which can be found online to try to sort this out but can't seem to reconcile what I'm seeing.

After running the self tests, test 50 (configuration status) reports the following... I'm trimming down to only items marked with question marks since those are indicating faults of some kind:

? CLK          0000.0005
? DZ            0000.4001
    00000001 00000001 00000001 00004001 00000000 00000000
? MEM          0020.0081   <--- This is the one that I think actually matters.. next line too
   00400000

As I read this, it's claiming on the MEM line to have 32 megs of RAM... but the next line seems to indicate only 4 megs of RAM.  Additionally, the 0081 seems to indicate that there's an error (manual says anything other than 0001 is bad) but then there should be another 8 digit code next to the 00400000 to indicate where the issue is.

The system exerciser doesn't shed any illumination.  If it is to be believed (and if I'm reading it right) it seems that everything is just fine:

B 0010  MEM    0135.0001   1 00A0   0 00:04:16

The .0001 in the exerciser, again, supposedly indicates success while the 135 indicates pages tested.

Any thoughts for a next step or some assistance if I'm completely misreading these?

Thanks!
