On the back of the VS 3100 is a DEC SCSI connector that I would like to
be able to adapt to a 'normal' SCSI I cable (Amphenol Blue Ribbon
connector). The 2nd choice would be to connect to once of the spare
cables inside the box...
Anyone have any info on an available adapter for this? Googling didn't
help much...
Long shot: was there ever a Pertec formatter made for the VAXstations? Or
SMD interface? Just curious...
Cheers

I am having problems with the pdp 11/04 I picked up last week. If I
power on with the machine without the extra cards, I get output on the
la36 with a $ prompt. So far so good. But with the card cage connected
the run light is permenantly on (ie. with halt switched), with no
output.on anything (There are two rs232, la36 and a display unit)
So the main questions are :
what could cause this ?.
The main cpu box has a 7856 which the la36 is connected to, also a 7800
which has an rs232 cable connected to it, how do I get the console
output to this so I can use vtserver on it ?
The controller card for the rx01 is in the extra card box, In the short
term can this be moved to the main box ?
It has a dead rk11-d and an untested rk11-c with no power supply unit
and no case. What sort of power supply runs this, I also picked up about
5 different power supplies with this, so one of these might do the trick.
Thanks for any help
Dan
well, of course, they wouldn't be cheap to produce on
a wafer like other chips.
Also, i don't think it is feasible as such will not be
able to handle all the power that would be o/p(heat i
mean), which would be in Watts!!(too high for ICs)
therefore i don't think it is possible to get led's
for the 75dpi screen

Just found the expansion chassis at a hamfest for $1, and wondering if
there is any documentation online for it. I'd like to try to see if I
can save some programs, etc.
It has the bus interface card, floppy controller, RS232 adapter, and the
32k memory module too.
Any of you TI fans out there please contact me off-list.

Not to disencourage you, but there are already several in the DECUS

I've been playing with my old Pro-Log M900 programmer this morning and
I've figured out how to duplicate 1702 EPROMs. But I haven't figured out
how to use the memory buffer in the programmer. I THINK I've figured out
how to read the buffer contents and change them but something is wrong.
When I change the contents and then try to list them, they're reset to all
FFs. Either I'm not changing them or I'm not reading them or when I switch
>from edit to list they're being reset. I also haven't figured out how to
dump an EPROM to the buffer or program one from the buffer. Anybody know
how to use the M 900? I have a manual for the M 980 but it doesn't help.
The main confusion seems to be figuring out exactly what the Memory Buffer
vs Normal switch does.
Joe
Evenin' folks,
OK, I've just finished (for now) trying to get a full POST out of the VAX.
It needed a dummy load to powerup with no cards or devices present so I used
an old suspect RD54. Voltages fine and stable so in with the CPU cards
and.....
it passes the CPU tests and stops at 3 on the LED. The VT220 shows '00000000
03' which I took to mean it hadn't found any memory. RUN light stays off.
'Fine,' I think, and put the 1mb memory board in.
Still stops at 3, and sometimes the 'ready' button and 'drive 1 write
protect' LED flash alternately. It hasn't got to accessing the RQDX2 yet,
I'm making the assumption that tests 2,1 and 0 are the same as they are for
most other microvaxen.
Has anyone got a copy of the MV I owners guide or know if it lives on an FTP
server somewhere? The backplate has the list of tests on and according to it
'3' is marked as '640K??' but it stops there no matter which mem board I've
got installed, and I don't believe they're both toast. I'm reluctant to
borrow a 4mb board out of one of my other machines in case it gets nuked.
Could be a suspect backplane I suppose.
Any clues?
Cheers :)

hey, u know what, building a single board computer
with an 8088 isn't all that difficult and a lot of
circuits are already available.
one can also design a custom based computer as per the
requirements.
infact, the only problem would be in loading the
monitor program, which can either be copied from
retail versions, or can written afresh(tested
ofcourse), and then used.

I have put this out on the list before, with limited response. I am
looking for a good (preferrably working) IBM PS/2 Model 25. I would
also prefer one with a hard drive of some kind.
Thanks
Dan
I've been trying to get an RD-54 to work with an SRQD11-B Controller. I
finally figured out the the SRQD11-B wants the drive to be select to
either 1 or 2, instead of 3. I now have another, more troublesome,
problem.
The drive acts like it is selected to both 1 and 2 at the SAME TIME!.
An access to either will illuminate the drives activity light.
Everything hangs after that. The controller works fine with a Quantum
Q540 drive. So, is there some kind of Jumper or something on the RD-54
that would cause this kind of behavior?
I will probably bring the drive home this weekend and try it on an
RQDX-3 just to see if I get the same problems. Of course, I'll change
the drive select to 3 first.
Anybody have a copy of the manual for the P&T 488 S100 card? I'd like to
buy/borrow/download one - and I'll be happy to scan and post if others
are interested.

Well, if no one else makes a claim, the older smaller capacity drives are
usually in demand for amateur radio clubs. I have a reserve here for my
local club (in northern NJ). As an incentive, most of these clubs in the US
are 501(c)3 corporations. You would be able to take these as a tax
deduction. Find comparables on a refurb site, save the comparable resale
value from when you donate as documentation of a resonable price, and count
them as donations at the end of the year.
Much of this also applies to older 486 computers. A lot of the software
still used on the packet backbone (where it still exists) will not run on
newer machines.
Of course, I am not an accountant (IANAA?), so please verify all of this,
especially the comparables bit.

I just decided to test a TLZ06 on my system, and it don't want to
work. I normally play with an Exabyte 8200, and that works just fine.
(This on a 11/84 with a CMD controller)
So it might be as some suggested, that the DDS drives aren't too happy.
I tried with a DDS2 tape in it, if that matters. The system sees the
drive, and I can mount and dismount tapes, and even eject them. Reading or
writing gives errors, though.
I have not verified the drive on any other system either, so there are
several possible problems here, but I thought I'd report what I can
anyhow.

I once used a dual opamp in an 8-pin DIL to do that. One half was the
receiver, one the driver. I knew that what I was driving wouldn't
overload the opamp's output, and it kept the chip count down (it was a
small microcomputer based on a Z8, on a board about 3" square).

M8029 RX02 DISK CONT
M7954 IEEE CONT
M8043 4510 MUX Card
M8012 Boot Card
This was a working unit until recently when I consistantly get
"checksum error KVR 00" on bootup.
I suspect the M8012 card...perhaps Eprom bad? I have no Docs. I have been
to http://www.binarydinosaurs.co.uk/Museum/Digital/minc/minc.php and talked
with Adrian Graham and he sent me to this list.
any help appreciated greatly.

Just been playing with some real DEC hardware today and trying to coax
some life out of a pair of RA81 drives.
Both drives are exhibiting the same fault - as soon as the RUN button is
hit they seem to try and spin up for a second or two before the spindle
motor disengages and the red FAULT light comes on.
I'm not back at the site where these are until next weekend now, but is
this a common fault that might mean there are a few obvious things I
should check first?
One drive was supposedly working when decomissioned at the site where it
ran; the other one was definitely running on the site I was at today the
last time it was powered up a short while ago. Curious that both of them
are showing the same fault.
I only had the RA81 user manual with me today - should be able to get
hold of the service manual for next weekend. However, I hooked a
terminal up to the diagnostic port on both drives. Issuing a "RUN DIAG"
command with the HDA offline shows all tests passed. Pressing the RUN
button as described in the manual gives the "Front panel function in
progress" message as expected, the drive tries to spin up and stops, the
fault light comes on, and I get dumped back to the RA81> prompt on the
terminal - it doesn't even try to run any of the diags that the manual
suggests it should do at this point.
Looks like something's overloading when the drive tries to spin up and
immediately shutting things down. The HDA is free to turn, belt tension
seems good, and the motor manages a few revolutions before it stops.
Unforunately I can't for the life of me remember what other lights came
on at the front of the drive along with the FAULT light :-(

Hi,
Does anyone have a service manual for the Citizen 120D+ dot-matrix printer?
I'm trying to repair mine - the interface cartridge connector is totally
shot and I can't ID it. It looks like a DIN41612, but it's two-row (both
rows populated) with 30 pins. The printer's connector bears the text
"030P2B-L14N 92-4-03".
Thanks.

It isn't a parallel port, it is a subset of the PC/AT bus, with x86 timings
and a big bag-o-hacks to get DMA transfers to run a LOT faster than it was
ever meant to run.
Friends of mine and I have build interfaces off of an IDE connector that
talk directly to 80xx peripheral chips because of the similarity in timing.
The bus mastering side of IDE (esp if you're using a PCI interface) is the
weird part.
I just bought a somewhat older laptop, though I hope you will all forgive
me if it is slightly younger than the borderline for the interests of this
group (I am not sure on which side of the line it lies.)
It is a Toshiba 4010CDT, which uses a Li-Ion battery, the subject of this
message. I am amazed at the number of contacts between the battery and
the computer (about 10) and wish to know their function. On the Internet
I find nothing. On account of the short life-time of such batteries I
want to install NiMH. I accept that I would have to use a separate,
external charger, even removing the reserve battery fro the charging
process, as the price of being able to travel with a back-up battery which
would not die after two years of having it around.
The problem is all those connections; I have no idea what they do and only
a couple of them are needed for transfer of power to the computer. At
least part of the rest must be communicating data about the state of the
battery, either for the sake of charging or for warning of the soon-to-come
shut-down for lack of enough power to continue. I would have to lie to
the computer in such a way it thinks it is monitoring a Li-Ion battery, but
to do it I need to know what the lies must say. Does anybody have a clue
what the functions of these connections are?
Keeping my fingers crossed,
Bob
More googling shows that the MV I and the MicroPDP can be very easily
interchanged since they share memory modules etc, so I dug out my 11/73 and
proceeded to spend a while tinkering with RT-11 again for the first time in
nearly 10 years - there were files on there I'd changed in april '94 :)
Looks like the RD54 (not the one I used as a load on the VAX) is possibly
fading 'cos I got some overlay errors, but anyway....
The PDP still runs fine with the M7551 memory from the VAX so I know it's
not a board issue I have with the VAX. Next thing to do I suppose is
'borrow' the PDP's cab to test the complete set of VAX boards, once I verify
the PSUs are the same. That's a job that needs a lot of space which I don't
have so I'll have to invade the kitchen next week when everyone else is out
the house and hope I don't run into problems :)

Hi,
Does anyone have a description of the .PIC file format for images found on
some CP/M machines? I assume the ones I am dealing with a DR Logo image
files, but am not entirely sure. They are a binary format that apparently
has the filename at the 0 offset.
Any help appreciated.
Thanks.

I have heard there is a trick with mg-1 power supplies not working ...
I cannot remember where i have seen it.
If you have not heard of this trick let me know and i'll try and remember
where i have seen it on the web

Some battery packs use separate leads for charging and to supply power.
Also most packs (other than NiCad) have a thermistor to control the charge
rate. Many also have a thermal circuit breaker. All of these require
additional contacts. The Li-Ions in particular often have the circuit
breaker since they are prone to exploding violently if they are improperly
charged or used. In addition, some of the contacts may be paralleled with
other contacts to increase the current carrying capability. You'll have to
break open the pack to see exactly what they're all used for. Li-Ion, Ni-MH
and most of the newer batteries have very exactly charging and use
requirements. I STRONGLY recommend not switching battery types. Save
yourself a lot of aggravation and replace the cells with the same type of
cells. Spend your money on buying GOOD cells and not the Mexican or
Chinesse made junk. I've had extremely good luck with the JAPANESE (NOT
Mexican!!) made Sanyo NiCads but I can't say about the other type cells.

Looks like lots of Q-Bus PDP-11 stuff, including a CPU and backplane.
It's up to a measly $10.50 with two days to go. Item # 2588111758

sigh... looks like the guy ripped apart a Unibus PDP11 system. There are boards
there for a Kennedy tape drive, SMD drives, and a Emulex SMD controller.
If it has been sitting for a while, reseat all the chips on each board,
and then reseat all the boards. You can start by minimizing the number
of boards in the system, try just the boot, memory and cpu boards, and
see if the error goes away or changes.
Chips do go bad, but many a time it has been oxidation on the pins of
the DIP that go into the socket that makes a mess.

Yes, I know some of the functions (boss had a similar Toshiba). Apparently,
it not only gives battery life/charge notification and monitoring, it also
has battery temperature (for what reasons, I do not know since it was
grossly inaccurate most of the time). There even was a diagnostic for
Windows and DOS(boot floppy) that could be run and interface with the
battery to find possible run time/length, stress test, possible recharge
times, etc. I only know of the utility from a Toshiba tech mentioning it
when my boss had a problem. I don't even know if that is actually available
to the public. It was sort of like a rudementary serial interface to a battery.

X.400 is a messaging (email etc) protocol; I think you've seen an Acorn
X.25 Gateway. They weren't one of Acorn's success stories :-) I
recall the Psychology Department at Edinburgh University had one, they
intended it to link their Econet lab to the ERCC network and thence to
JANET. It's a box with a BBC motherboard and some extra gubbins in it.
You'd be better to run something like !Gateway on an Archimedes or
RISC PC with an Econet and an Ethernet interface.
