Seeking information on some Qbus disk/tape controllers: Dilog DQ37, Emulex QT131 and UC07

Hi, All,
I was going through a box of "interesting" cards last night and I came
across three cards that I'm looking forward to using:
o Dialog DQ37 - an S-box-handle Qbus SCSI controller
o Emulex QT131 - a Qbus Pertec tape controller?
o Emulex UC07 - a Qbus SCSI controller
I found the UC07 manual on Bitsavers, so I'm good there for setup and
configuration, but I was curious if anyone knows about different
firmware revisions I should be aware of or seek to put on the card
(I've owned plenty of Emulex communications controllers, and done
plenty of firmware swaps on those, and since they put firmware (ROM
chip) upgrade instructions in the manual, it makes me practically
expect to have to do something to it).
I could not find more than a couple of comments about the QT131, but
I'm reasonably certain whatever jumper settings are on there are a)
the defaults, and b) just fine. If anyone here has any experience
with the QT131 or even better, a manual, that would be appreciated.
As for the Dilog DQ37, I can find nothing except 3rd-party resellers
offering to sell me one if I click the "give me a quote" button. The
ones I have (2) appear to have the single-ended SCSI portion of the
board populated and have a large bare patch that, from the component
values on the silkscreen, seems to me to be for High Voltage
Differential. No biggie. I don't have any HVD drives anyway. I
don't own any S-box hardware, so "just plug it in an see what it looks
like" is not the preferred method - I'd like to know more before I go
further. I'm especially wondering if this is a TMSCP-only controller
or if it will do MSCP and/or TMSCP, and if there are any firmware
variations I should know about.
So... anyone here know about these cards or where to find docs
(besides the UC07 docs on Bitsavers)?
Thanks,
-ethan

Did you compare the QT131 with the QT13 manual to make sure that's not what
it is instead?

I had not - I read "QT131" on a label on the board and read "QT135..."
in the Emulex directory on Bitsavers and did not connect that both are
really the QT13.
That looks like the right manual. Thanks for pointing it out.
Now to find out more about the DQ37 and I'm all set.

I didn't think to check Dilog, and from the state of their webpage
(broken links to button graphics, 403s on a documentation link...) I'm
not missing much. Good to see at least a sentence about many of their
products, though.
SQ3703A BA4000, SCSI, TMSCP, Quad Height. Replace with
SQ3709

Yes. I will have to examine my boards carefully to see if they are
marked as SQ3703s, SQ3706s or SQ3709s.
If I'm understanding it right, the older boards (firmware?) are one or
the other, but the newer model handles mixed devices on the same bus.
Thanks again for digging that reference up.

In addition to the quad wide S-handle SQ3706A I have I also have a dual
wide SQ703 and a SQ706. Interesting that the SQ703 has the transceiver
daughter board but the SQ706 does not. It's not just different firmware
between the SQ703 and SQ706 I have. The TMSCP board worked when I first got
it but has died since the. The MSCP board works well.

Also, do you really mean SQ37 instead of DQ37? If so that is just part of
the model number with the SQ37 screened on the board and a smaller sticker
next to it with something like 06A.
I have an SQ3706A, REV H, firmware REV L.
I'd have to plug it into a system and power it up to remember if can do
both MSCP and TMSCP at the same time.
Mine is also the s-handle version with an MMJ config port.

Hmm... I remember the ?Q37 in copper in the upper-left corner of the
board, but I don't remember any stickers next to that. Perhaps it has
the number in a easier-to-interpret fashion somewhere I wasn't
looking.
I'll have a chance late in the holiday weekend to check the board
again. I'll keep your numbers in mind when I examine the board.

I'm not as gung-ho about needing it to do both at the same time (the
Emulex UC07 can't... you pick one or the other, probably part of the
reason for the UC08, which is two independent UC07 circuits on the
same physical card). If it does MSCP (disks) at all, I'm good with
it. I have SCSI DAT drives, though I'm unlikely to need that on a
MicroVAX or PDP-11, and I do have a TSZ07, but if I can't hang it on
the same bus as disks, I won't lose any sleep. I have other options
(like the QT131 and a TU80) for Qbus magtape.
Mine is also the s-handle version with an MMJ config
port.
Yep. I do have the MMJ config port - the wires pretty clearly trace
down to a MAX232, so I was planning on plugging in a terminal if I
can't find docs, just to see what the board tells me.
Here's an edited list of Dilog docs on Bitsavers...
2120-0184-E_SQ706A_Jan90.pdf
2120-0209_SQ739_SCSI_MSCP_Disk_and_Tape_Controller_Oct91.pdf
SQ706A_SCSI_MSCP_Disk_Controller_Oct89.pdf
The SQ706 and SQ739 are dual-height cards.
Thanks for all your help so far,

OK... looking at my hardware...
The UC07 has a paper-label on the EPROM marked G143M and the 40-pin
chip with the serial number and barcode says "Rev F" (there's a "Rev
D" written on the board in Sharpie up by the SCSI connector).
My Dilog boards are, according to the paper labels in the upper-left
corner, SQ3703As. One is marked Rev G and looks clean. The other is
a Rev E with a few green ECO wires (the Rev E board has an EPROM
marked "Rev G", and the Rev G board has firmware marked "Rev H".
I'm guessing there isn't a lot of info out there to attempt to see if
it's possible to "convert" an SQ3703A to an SQ3706A in the field, but
if anyone knows anything about both boards, I'd be game to try if it's
EPROMs or PALs or whatever.

Found almost nothing for them.
I have a board LAbeled SQ703 where the 03 is on a paper label and the SQ7
is printed on the board. Have repaired it sometime, it is working as TMSCP
controller. It has an 10pin Connector for an Terminal to set it up on the
Interface connector side. I remember that I put the rom image from a 706 on
it (shadoo sent me one) but it doesn't work as 706.
I know that there is a 739 that can make both, MSCP and TMSCP...

Right. Found that with no problems, though their own docs describe
the UC07 as a quad-height Unibus card - I'm sure that's just an
ancient cut-and-paste error.
All the settings are in there; that's the important part. I can check
if it's strapped to share the bus with an RQDX3, a common arrangement
(to keep the floppies active). I think that would make the first
drive on this card DUB0: when booting to VMS, but ultimately, except
for typing habits, it doesn't matter what the drive name ends up as.

I would be interested to hear any stories or if anyone happens to have
Release Notes or ECO sheets for different ROM versions. ISTR the
processor on this is an 8031, so it's not impossible to decompile and
diff the different ROM versions, but it's probably not worth the time.

Shame it isn't that easy, but I rather expect it's a ROM and PAL
difference, since MSCP and TMSCP controllers use different address
ranges. Any differences in SCSI command sets from tape to disk drives
would be a firmware issues; any differences in bus interaction would
be (mostly?) PAL issues.

Right. Just like the 3703A and 3706A were replaced by the more flexible 3709A.
Since I don't _need_ SCSI TMSCP, it reduces my interest in laying
hands on a BA4000-type chassis. I do have that KDJ11 with the S-box
handles, so I'm more likely to mod that than go with an S-box (I have
a stash of real DEC Qbus handles from the place where we made Qbus and

Like you most people don't need an TMSCP SCSI Controller. I'm using them in
conjunction with some Tandberg quarter Inch drives, have install tapes
build with simh for RSX11M, RT11, XXDP ans 2.11 BSD and I'm using this to
transfer data between the simh on my unix pc and the PDP11s.
I don't looked that cwclose to that board that I could say how the address
decoder is made. It could be an register written by firmware and a
comparator too, this isn't much more hassle as an programmed Pal (but I
remember that I have seen many of them on that board).

I don't have an BA4000, got an DELQA sometimes from Ebay and removed the
SBOX Handles to put it in a straight 11.
You don't have some of the QBus Hanldes left over? May be you remember that
we build some punched universal Boards lately.. (Arghh, forgot the right
description AGAIN).
Have a KA630 with memory laying around too, but an PDP11 is more fun for me
(don't know why). iBut I had Quasiarus running on the KA630.
If I want VMS I'm booting the VS4000/90...

I have a few, not hundreds. I have a lot more hex-height handles for

I enjoy playing on PDP-11s, but the 64K process limit is a bit much
for serious work. I've done _real_ work on VAXen.
If I want VMS I'm booting the VS4000/90...
Right. I only recently got a slower (/60?) VAXstation 4000. Prior to
that, I was struggling to get the SCSI patched ROMs and driver onto a
VAXstation 2000. I never did get that working. I still have a lot of
the VS2000 hardware including the 8-port expansion and an external MFM
drive cable set. Only one ethernet option, sadly. I keep meaning to
test and box up most of my VS2000 hardware and sell off the stuff I
don't need, but other more important things keep me from getting it
all together. Before MicroVAX3100s and VAXstation4000s got cheap and
available, the MicroVAX2000 was the only way to get a small VAX at
home for under $1000. That's been a few years, though. ;-)

On my SQ3706A, REV H, I have the following socketed GAL devices:
13U 92771A
18U 92769A
19U 92773A
26U 92774A
34U 92770A
57U 92775B
74U 92772A
The firmware is U46 92734, REV L
57U is the only device that is not a Nat Semi GAL, and the only device
with a 'B' suffix. That plus its location adjacent to the DILOG QBIC
ASIC leads me to guess that device is most likely the CSR decode
device. I suppose it wouldn't take much to check the pins of this
device and see if they lead to the BDAL lines through the AM2908 quad
bus tranceivers.
What part labels do you have on the socketed GAL devices on your
SQ3703A? Do they happen to match the part labels that I have on my
SQ3706A except for U46?
I might not take too much to figure out how to convert a TMSCP SQ3703A
into an MSCP SQ3706A.
Ok, I'm now getting lined up to acquire an SQ3703A. When it arrives
I'll compare the two and see if I can figure out how to do a
conversion as I did with CMD CQD200 and CQD220 boards.

This is an old thread. I finally got around to taking a look at both
my DILOG TMSCP SQ3703A REV G and MSCP SQ3706A REV H controllers side
by side. All of the DIP parts in sockets with labels have the same
numbers on them, except for the EPROM.

The firmware on the TMSCP SQ3703A REV G is 46U 92782, REV J
The firmware on the MSCP SQ3706A REV H is U46 92734, REV L
As a quick test I replaced the EPROM from the TMSCP controller with
the EPROM from the MSCP controller and now it does appear to be
functioning as a TMSCP controller. I did have to change the CSR
address from the default TMSCP address to the default MSCP address in
the controller configuration menu but didn't do anything else and was
then able to boot from a SCSI DISK device.
I'll have to dump the EPROM contents (27512) in case anyone else has a
SQ3703A TMSCP controller they would like to try as an MSCP controller.

This is an old thread. I finally got around to taking
a look at both
my DILOG TMSCP SQ3703A REV G and MSCP SQ3706A REV H controllers side
by side. All of the DIP parts in sockets with labels have the same
numbers on them, except for the EPROM.
Cool!

Nice.

Naturally.

Very good to hear.

I would love a pointer to this when you do it. I still don't own any
S-box hardware but I'd be willing to drill out the rivets and replace
the handle with one that will fit in my BA23 or BA123 (or if I could
find one of those 4-slot S-Boxes that was a DEC comms controller, I do
have one of the S-box CPUs for it that is really a PDP-11/53 board
with different ROMs - that plus an SQ3706 would be a good start to a
system).
Thanks!

I dumped the SQ3703A (TMSCP) and SQ3706A (MSCP) firmware (27512) from
my two controllers boards (quad wide). This firmware is not
simultaneous TMSCP and MSCP. That would be the SQ3709. I have never
seen one of those and have no idea if it might actually be the same
board with different firmware. If anyone on the list happens to have
an SQ3709 I'd like to see a high resolution picture of one.
I also have examples of SQ703A (TMSCP) and SQ706A (MSCP) controller
boards (dual wide). These two boards have physically different
designs. I haven't tried swapping the firmware around on these two as
I had doubts that it would work. These two are also not not
simultaneous TMSCP and MSCP. That would be the SQ739, which I have
also never seen.
So anyway, I don't have anything interesting for your SQ706A.

Thanks for your efforts anyway.
At first read the SQ3706A seemed to me as a SQ706A with SBox handles.
