I've got a TD Systems Viking "VIK/QDA" QBUS SCSI controller, which I'm
trying to use. Does anyone have documentation for this thing? It's
properly configured to be at the primary (disk) MSCP controller address,
and looks OK from the QBUS side, but I can't talk to any SCSI disks that
I connect to it.
This is what "show qbus" gives me on my VAX 4000/300:
>>>show qbus
Scan of Qbus I/O Space
-20001468 (772150) = B440 RQDX3/KDA50/RRD50/RQC25/KFQSA-DISK
-2000146A (772152) = 0B40
-20001600 (773000) = 0A0F
-20001602 (773002) = 01FF
-20001920 (774440) = FF08 DELQA/DEQNA/DESQA
-20001922 (774442) = FF00
-20001924 (774444) = FF2B
-20001926 (774446) = FF32
-20001928 (774450) = FFA6
-2000192A (774452) = FF9E
-2000192C (774454) = 8400
-2000192E (774456) = 1030
-20001F40 (777500) = 0020 IPCR
And, this is what "show uqssp" gives me:
>>>show uqssp
UQSSP Disk Controller 0 (772150)
-DUA0 (@0)
-DUA1 (@0)
-DUA2 (@0)
-DUA3 (@0)
-DUA4 (@0)
-DUA5 (@0)
-DUA6 (@0)
So, it's there, and responding to the CPU (and yes, it's the only MSCP
device in the system, so it's not conflicting with anything else).
I've tried setting the SCSI drive to several different SCSI IDs, and I've
used drives from 540MB to 6GB in size, with no luck. When I try a "show
uqssp" or a "boot dua0", the controller blinks its red LED, but the
activity light on the drive doesn't light up at all (the SCSI ID on the
drive was set to "0" when I tried booting from it).
Any ideas?

So, back to my 8-inch drive problem... Would a Shugart 851 be an
acceptable substitute for a Qume 842? The client tells me that any of the
following will work in his Fairlight CMI synthesizer:
Qume 242
YE Data YD174
YE Data YD180
Mitsubishi M2896-63
I'm not clear where he got this list. I'm looking at the manual for the
Qume and it claims that it's an electrical and mechanical match for the
Shugart 850. Is this a close enough match?
Also, the client is in the zipcode 53153. Is there someone near there who
I can coax into taking a look?

I've got about 15 of these to dump or give away. These are the
gizmos that fit in a 5.25" HH drive opening and hold a removable tray
with a 3.5" hard drive in it. Mostly IDE, a couple are SCSI-I and a
few have built-in-fans. Some are still NIB.
These do not work with the UDMA4 80-conductor cables (well, they do,
just not in UDMA mode).
The lot is yours for the shipping cost.

Chuck
I've got 4 or 5 of these little boxes for 120v operation that hook in
series with a PC keyboard cable (5 pin DIN) and the mains supply for
the monitor (3 prong line cord; female IEC cord). They've got a 4-
position DIP switch on the back to vary the time between 10 and 40
mintues. The idea is that if the DIPswitch selected time goes by
without any keyboard inactivity will turn the monitor mains supply
off. Some are the "Monitor Miser" brand; others are the IBM Options
"Display Miser" brand--they're identical internally.
Free to anyone who wants the lot and pays postage.

I've got a Cipher 525 full-height 5.25" QIC floppy tape drive--
writes DC600A tapes. New, in original bag and box.

Yup, I know it's been asked for here time and again, but I'm going to try
and keep it in folks minds ;)
Would anyone have the DEC boot rom for the M9312 that boots off TMSCP TK50 &
TU81 (MU)? Please check your M9312 boards and your PDP-11/44 boot roms for
rom "E39A9" or part number "23-E39A9".
If you have it, I (and a few others) would love if I could borrow it to make
an image.
Best regards,
Jay West
... does anyone else have a Baydel STBC multifunction card that they
could read the ROMs off for me?
I contacted Baydel, but sadly they'd just pitched the last of their QBus
stuff prior to a move a few months ago :-/

Because of space constraints I use a Samsung LCD-TV for my HP 86B,
HP 9915A/B computers and my HP-IL video coverters.
The display quality is very good, but the LCD-TV does not have the
same flexibility in adjusting the display as analogue monitors, so
the leftmost 1 or 2 characters are missing. On a Dell LCD monitor
with composite input the display appears correctly, so results may
vary between LCD panels.

Hi all,
I am looking for an M8637 PMI memory module to make my 11/84 happy.
1 Mb or 2 Mb, it's not really important. Who has a spare board and
is willing to sell or trade it?
thanks,
- Henk.

Hey, nice machine!
As a person who actually still keep one of these beasts alive, I have a
few comments that might, or might not help you.
First of all, it's a fairly loaded machine. You have atleast three
unibuses, and since you have a TU79, I would think you also have
massbus. Really nice. (First time I've actually seen a TU79, btw. Only
seen TA79 before.)
However, the buts... There is no memory in the machine. Do you keep
those cards in a box somewhere, or are you missing them? Also, if you
look at the bottom of the large cabinet, there is a box there, with a
TOY in it. That TOY contains four lead batteries, that should not be
left unattended for more than six months, or they will probably go bad.
Without batteries, the machine will not boot. I think I have some
document somewhere on how to bypass this if you don't have the
batteries. Let me know if you ever get as far as trying to fire the
machine up.
Also, the smaller cabinet for the machine, that holds the first unibus
box, the console Q-bus, and the RL02 drive is a very important item. The
RL02 drive holds the console medium. This pack is extremely valuable for
you. Without it, you'll have a inoperative machine, since the frontend
boots from the RL02, and the frontend then loads the machine with all
the microcode also read from the RL02. Almost all diagnostics are also
on the RL02. Store it in a good place, and try to make copies of it.
Oh, and is it an ASR-35 I see in the background? :-)
The 86x0 machines are wonderful, and loads of fun to play with. As long
as you have the power and cooling for them.
Oh, and make sure you hook the power up right to it, since the fans for
the machine are real 3-phase motors, and will run backwards if you get
the phases wrong. And that will soon damage the machine as well.
Johnny
