Hi all --
The VAX-11/730 we have running here at the museum has developed a fault
that occurs only sporadically, usually days apart. Running the complete
diagnostic suite for the better part of a week reveals this:
SECT TST ERR EXP REC OTHER MSK MODULE
ENKCC 33 08 000000FF 000000DF N/A FFFFFF00 M8391 M8728
Re-running only ENKCC, this error is repeatable (though it still takes a
couple of days for it to occur). It helpfully points out the MCT (M8391)
and memory boards (M8728) as possible causes; we have spare M8728s and I've
swapped them around with no change in behavior. I have a spare M8391 in my
own collection but it fails in a completely different way so that's not
much help.
I cannot find any real documentation for ENKCC so I don't know what TEST 33
is doing, nor what ERROR 8 indicates in this context, though it seems we're
dropping a bit somewhere :). Anyone out there sitting on a pile of 11/730
documentation?
Thanks as always!

According to the Fiche I have for ENKCC version 1.2 (Diagnostic Listing)
dated September 1982 - VAX 11/730 MCT MICRO
Test 33: Moving Inversion Test on Array (M8728 ARRAY or M8391 MCT Module)
Error 8:
"Moving Inversion failed on descending path with background of 0's Bit
being toggled is either bit 0 or bit 1"
"If a failure occurs the address being accessed will be in LS 9 and can
be examined via EX LS 9. The bit being toggled at the maxiumum rate
will be in WR 3 and can be examined by typing EX WR 3. OTHER data is
not used so as to insure that the test runs as fast as possible."

Thanks, Jay! Any chance of getting these scanned at some point? To the
best of my knowledge these listings haven't been archived anywhere.

Fiche - I have no ready way to scan them. Hundreds (in several
different DEC groupings). Not likely anytime soon.

If you're willing to send them out, the LCM would be happy to scan them and
get the scans off to Al, etc.
Thanks again,

Sure. Works for me. There are, in all, likely well over 1000 fiche,
maybe even more than 2000. Many fiche have multiple documents on them
(e.g. module documents), some have more than one fiche to a document
(e.g. diagnostic listings).
All told, in their boxes and envelopes, 25lbs or more, so maybe 30-35lbs
shipped. The first two listed below are in wooden boxes, the second two
in DEC-supplied plastic "index card" type boxes. The DEC-O-LOGs are in
list DEC-supplied plastic flip front boxes, and the listings are in
plain brown envelopes.
FYI, if I recall correctly these originated from the Univ. of Wisconsin
Instrumentation Systems Center (ISC). I know that I obtained them via
the UW SWAP (Suplus With A Purpose) program at least from a paperwork
standpoint, but I don't know that I recorded exactly where they originated.
Some questions:
1) Would you want me to sort/curate them first, or just send the boxes?
(i.e., check for duplicates, sort, etc. Quite a few hours of work -
Probably more than 40.)
2a) I am assuming you would send them back to me at some point.
However, I also have to say that if the scans are good, I could not
expect to find a better home for them than the LCM. Would you want to
keep them at the LCM?
2b) How long might it take you if you want multiple sets and expect to
return them. If really short, I could send them all. If longer, maybe
one set at a time.)
3) I have several sets. Which of them would you want to scan?
All are from the DEC Maintenance Documentation Service (MDS)
LEVAX - 000016 (VAXen and associated peripherals) Circa 1982-1986
Probably around 600 fiche.
Index, Bulletins, Hardware Manuals, Ill. Parts Breakdown,
PM (not sure what this is, only one: RA60 to RL01/02,
Diagnostics (VAXen and associated peripherals)
Wirelist (DR11-B only),
Technical Information, Module Assembly (pwr supplies, cards, etc.)
A bunch of update bulletins (would take time to go through and
insert/replace in their proper homes - though these may be the
replaced ones removed - hard to tell.)
PDP11 - 001926 (PDP11 and associated peripherals) Circa 1980-1985
Probably around 500 fiche
A few Ill. Parts Breakdown,
Almost all the rest are diagnostics
I wonder if the above two boxes were merged or partially merged.
HTERM - 000146 (Hardcopy terminals?) Circa 1974-1985
Maybe 100-200 fiche
Index, Bulletins, Hardware Manuals, Ill. Parts Breakdown,
Diagnostics, Wire Lists, Technical Information,
Module Assembly, Misc "General" documents,
Update bulletins (much like the Vax one)
VTERM - 000171 (Video Terminals?) Circa 1974-1985
Probably 100 or so fiche.
A couple of odd manuals up front (KW11L, DR11-K, A/D cards,
TM & TU Diagnostics, Index, Bulletins, Hardware manuals,
Ill. Parts Breakdown, Diagnostics, Wirelist,
Technical Information, Module Assembly,
Misc "General" documents, Update bulletins.
MFDOL - 17 MDS DEC-O-LOG Less than 50 fiche
MFDOL - 18 MDS DEC-O-LOG Less than 50 fiche
(DEC-O-LOGS appear to be mostly field change order documents and spare
parts lists.)
AH-H159C-SE VAX/VMS V3.0 SRC LST MCRF (About 100 Fiche)
AH-N471A-SE VAX/VMS V3.1 SRC LST MCRF (About 25 fiche)
AH-P762A-SE VAX/VMS V3.2 SRC LST MCRF (About 25 fiche)
AH-V324A-SE VAX/VMS V3.3 SRC LST MCRF (About 25 fiche)
AH-W742A-SE VAX/VMS V3.4 SRC LST MCRF (About 25 fiche)
AH-Y852A-SE VAX/VMS V3.5 SRC LST MCRF (About 25 fiche)
AH-CK92A-SE VAX/VMS V3.7 SRC LST MCRF (Less than 25 fiche)
AH-FY84A-SE VAX/VMS V4.2 SRC LST MCRF (About 100 Fiche)
AH-GZ64A-SE VAX/VMS V4.3 SRC LST MCRF (About 25 fiche)
AH-HP48A-SE VAX/VMS V4.4 SRC LST MCRF (About 200 Fiche)

When I was working through some issues on my 11/45 last year, Jay tracked down several
DEC-O-LOGs in these fiche that I had not been able to find anywhere else. I would be
pretty psyched to see otherwise missing DEC-O-LOGs and diagnostic listings scanned!
