I found various DEC (Qbus?) boards at my local tame recycler earlier.
They're scheduled for preprocessing this evening (e.g. ceramic ICs pulled
and diverted into different pile due to higher gold content), but I may be
able to get them a stay of execution (as of now I've got about 2 hours in
which to let him know before I'm awol for a family event).
Anything below strike anyone as being worth saving (vs. common as dirt
serial interfaces etc.)? I'm not sure at the moment if I can rescue the lot...

M8061 x 2
M8044 x 2
M8190
M8043 x 2
M7961
M8067 x 2
M7856
In addition to those, a board branded Dilog CQ1610, another marked PXX-2
with four SC44077P ics in the center, and a memory board marked 980110014
containing 128 mmc3764 RAM ics. Also several Emulex boards which didn't
contain anything that was obviously a part number (from memory a couple
that were "full width" and three that were "half width") - I'm
guessing
they're probably tape controllers, but they might be hard disk.
Working status unknown, but cosmetically they looked good. It sounds like
the previous owner had complete machines which he split and scrapped at
some point in the past, and this box of boards had sat around in his garage
since.

always useful to have a serial card, the UNIBUS standard is the M7856,
often 9600 b
6:07 p.m.
The M8190 is likely to be of interest to someone since it?s likely to be a 11/84.
Personally I?m interested in one or both of the M8061?s which are Qbus RL02 controllers
and would cough up some bucks to buy off the recycler.

Dilog CQ1610 is a 16-linse serial card (I think)
Anything Emulex with a 50-pin connector on the top is probably a SCSI card. Worth saving.
I don't know where you are, but most of it is probably worth saving, someone,
somewhere is probably looking for that stuff. If it's working, that is. Maybe even
for repair parts.

Yeah, I started throwing numbers into Google after I posted, and I think
that one came up empty. Maybe I wrote it down wrong.

Hmm, that sounds useful. Makes me wonder how far things are from being able
to make a functional system, assuming a backplane and suitable PSU...

I'm up in northern MN. First time I've seen any DEC stuff in the ~12 years
I've been around here.
Anyway, I just told the guy to hold off on execution and I'm going back in
next week with a view to just buying everything, then I'll figure it out
later. My wife just gave me a look ;)

Neat! I used to have a friendly scrapper for a friend - got a BA23
from him, and some VAXBI boards (because was quite
happy to pay him
well over the gold value) - but that was coming up on 20 years
ago.
Also several Emulex boards which didn't

Emulex made a lot of disk and tape and serial comms interfaces. If
they are dual-width, they are Qbus for sure. If they are quad-width,
they could be Qbus or Unibus, though in my experience, Unibus Emulex
cards are hex-width, taking advantage of the board space to load up
features/port count.
Thinking back to the Emulex CS/21 16-port serial card, it has a pair
of 50-pin connectors, but the array of 40-pin DIP UARTs and the
cluster of EIA line drivers by the connectors means it's fairly easy
to see it's a serial card. I don't know if Emulex ever did Qbus
serial cards, so a dual or quad-height card with one or two 50-pin
connectors is more likely to be SCSI, disk or tape or both, than
serial, so all I'd advise there is looking for tell-tale signs of an
actual board name/number or the characteristic parts associated with
SCSI vs EIA serial.
They also made ESDI and SMD interfaces, but the pin count there is a
dead giveaway.

New subject: DEC and Emulex boards (was: DEC boards at recycler)
I hauled the DEC + friends boards home earlier which I mentioned finding on
the list last week.
The "unknown" board I'd noted down as M7961 is actually M7951, which Google
suggests is a DUV11 interface board (whatever one of those may be ;-)
The board with the 128 mmc3764 ICs on it has what I think is a National
Semiconductor logo on it. Google's no help in IDing the 3764, but I'm
guessing it's a 64kx1 DRAM or related.
Next up we have the Emulex boards - all "FH" ("full height", 4 bus
connectors) or "HH" ("half height", 2 bus connectors):
TU0310401, FH, 2x50-pin headers on outer edge.
SU0210401, FH, 1x60-pin and 2x26-pin headers on outer edge.
CU0210402, FH, 2x50 pin and 1x16-pin headers on outer edge.
QD3310401, HH, 1x60-pin on outer edge and 2x26-pin headers just inboard.
QD2110402, HH, 2x20-pin headers on outer edge, then a 34-pin and 10-pin
header just inboard.
I think all of these boards have at least one 40-pin IC on them with a
label which generally bears a number close to the ones on the PCBs quoted
above; I can reel those off if needs be.
But anyway... anyone know from that what any of these boards are? I suspect
there's some SMD in there, possibly ST506/412 in the case of the one with
the 34-pin connector. Not sure if I'm lucky* enough for any of the others
to be SCSI though, or if they're some form of tape (or something else
entirely).
* I only say that because I have a vague notion to see if I can rustle up a
backplane somehow and get a minimal system running; it would be kind of fun.

The QD33 is an SMD controller, the QD21 is an ESDI controller. I'd wager
the TU03 is a Pertec-compatible tape controller. Nothing looks to be SCSI

Rats, I was leaning toward there not being any SCSI ones - the ones with 50
pin connectors didn't seem to match anything I could find online.
I hear that the PSUs that went with the systems these boards came from
might still survive (they did as of last week, anyway), but the word is
that everything else - drives, racks, cables etc. - went to landfill long ago.

There is a separate metal recyclers north of town and I expect they might
take complete systems, but I think they've only been around a few years and
perhaps weren't there "back then". I also know they outright refuse to sell
anything that hits the yard, so it's not as though their existence would
have saved the original hardware.

I don't know if there were any wide controllers (68 pin) or what they
ran from the controller at this time.

Right. The connectors also bear that out (SMD is 1x60 + 2(or 4)x26,
Pertec interface is 2x50 (not exclusively), ESDI is the same number of
pins as ST506/MFM, 1x34 and 2(typically)x20, but not interchangable).
ISTR it's not hard to find QD21 and QD33 controllers, but the SMD and
ESDI drives aren't as abundant as they once were.
The CU02 is a serial mux, and Emulex (and DEC) did make 50-pin mux
output connectors for Unibus boards (CS/21, DZ-11...). You will
probably see on that CS02, 8xSCN2641 UARTs and a bunch of 26LS32
differential line receivers (RS-422 not RS-232, if so) or something
functionally similar.

It's the Qbus version of a DU11 sync serial interface that can
implement character-based (not bit-stuffed) protocols. ISTR that
includes HASP and 3780 but I'm not sure what else off the top of my
head.
