I have gotten my PDP 11/73 to
start up and go through an initialization
script for RSX-11Mplus. However, I do not
know any uids/passwords, so I cannot
login; I can only watch the script go by.
I am able, while the script is running, to break
into MCR and run commands like PDP and DMP.
I am able to dump in octal
some of the files like [0,0]001054.DIR;1.
Does anyone know where the user names/passwords
are stored? My memory says that the maybe
they are not encrypted? Is that so?
TIA,

Yes, cctalk is not the totally off-topic free zone that cctech is. However,
do NOT interpret that as a "anything goes" policy. I've sat back and watched
the past few days of crap threads and I'm a little tired of it. More
importantly, I've received numerous complaints.
OFF topic posts on cctalk ARE ok. But I think we're all adult enough to know
what is pushing the envelope. Sure, go off topic, that's what this list is
for. But extended threads on religion, politics, etc. that are little more
than pi**ing contests are just off-base.

I believe LTI is Lapis Technologies.
They made video cards for the Mac. I would guess it is probably a video
card of some kind. Many of the older full page display cards had 9 pin
connectors. I don't know if they used a standard video output or if they
had to go to the monitor they were meant for.

Probably just artistic license on coloring the board. I have seen blue
video cards before in the Mac.

I recently received a bunch of stuff, including 3 each BC26V-12 SI disk
cables, frequently used with RA60, RA80, etc. disk drives. I have no use for
them, so if anyone wants them, they are available for the shipping expense.
Contact me off list if you are interested, tell me how many (1-3) you want.
These cables came from my previous employer and were removed some years ago

Hi,
A PDP-11/04 on ebay

748&rd=1
I have to start by stating I am in Australia. Our dollar might have
crept back up to a smidgen over 60 cents US today, but the opening bid
on the PDP will still be considerable, then add international shipping
and ooooooh ouch. But despite all that I am still toying with the idea
of bidding on the item. I do need a little assistance before making a
definitive decision. For those unaware the item was listed before
recently but was passed in unbid. I did not get interested last time
since the description did not list a CPU card, and the seller did not
reply to an enquiry regarding a CPU card. I notice that this time there
is a CPU card listed (M7263). My quandary is over the seller's comment
that the "Unit powers up and reads 0002777" although the pictures have
it reading 000277. My worry is that the unit is severely broken. Can any
take a stab at guessing what might be wrong, is it possibly just the
lack of a boot device (floppy of hard disk)?

Hi all, I am trying to accelerate my plans to get my Intel MDS
up and running... I have a VAXStation II/GPX with two monitors,
mouse and keyboard. I think I have all the docs and disks for
it also. It belonged to a friend who gave it to me because he
was just going to throw it out. It was working for him, but I
don't know the first thing about getting it running or do I really
want to take on another project. What I am looking for is to
use it in trade for an Intel MDS 225/230 development system.
I don't need software or manuals for the MDS (I have all that).
I don't even need any of the ICE modules. I also have an Intel
iPDS with software that I would consider in trade also. Any one
interested?

I don't think you can put a KDA50 in a BA23, isn't the reason that
"Corporate Cabinets" have dual BA23's in the rack so that you've got enough

I'm not aware of ANY lies by the current
administration, no less "lies and more damnedable
lies"
Also, you can't hold this administration responsible
for the misdeeds of past administrations.
In fact, I'd call the previous administration one of
the most dishonest and criminal administrations this
country has ever had.
Luckily our system of government is such that people
like this cannot remain in power for too long.
As for the rest of what you say, I don't have any data
for or against it.
America is a representative republic. Not quite a
democracy. And yes, the government does things that
the people don't necessarily like or agree to.
Given that, I still believe we have the free-est and
best form of government on the planet.
It is not corruption or mistake free. Nor is it free
of the normal human expressions of greed, ego, hatred,
and agression.
It's still head and shoulders above all other
government systems on the planet.
Considering the broad areas in which the U.S. is
invlolved in, the huge amount of AID it gives to the
rest of the world, you have to see that basically we
are a good country.
I would like it to be perfect, but that's not possible
in human affairs. It could certainly be better. And
what I like about Bush and his administration is that
he got right to the task of setting right all the
wrongs of previous administrations he could find and
fix.
I know he will be relected in 2004 with a landslide.
It's a shame he can't run for a third term. Cheney
will probably not be able (or willing) to run for
President in 2008.
Before the election, and before I saw Bush in action.
I was sure he'd be a one term President and that
Hillary Clinton or maybe Al Gore would run in 2004 and
take back the Presidency for the Democrats.
Now, I'm sure that won't happen.
It's amazing that you can call a liar, a man whose
reputation is largely made by his truthfulness and
trustworthyness. As Governor of Texas he kept most all
of his promises. And left the state in a much better
condition than it was when he took office.
You may not like his policies, or his decisions. But,
that doesn't make him a liar.

We lost a Lear Jet here at the Warrenton, Oregon Airport when it hit a 1500
pound Roosevelt Elk halfway down the runway on an early morning takeoff last
October.
Totally trashed the Lear Jet, the Elk was in 500 pieces but the pilot and
passengers were OK and able to get out of the plane before it totally burned.
We had a herd of about 50 Elk living on the airport flats. Now they have an
Elk proof fence that I swear will cause hard drives to fail when you drive
across the grat-t-t-t-ting to get to our local UPS drop off center.
The Lear Jet was over 10 years old so to get this on topic does anyone know
if the older Lear Jets used computers and what kind?

The thing to remember is that the controllers in that price range are tape
only. For example, that MTI QTS-25 was tape only as I recall (or to put it
another way, I don't recall buying any SCSI controllers on eBay that weren't
tape only :^)
The jump in value from Tape only to disk only is pretty huge, then there is
a lesser jump in value from Disk only to Disk/Tape.

I'd recommend RA7x instead. The RA9x drives are 8", while the RA7x drives

Two questions.
First, has anyone here emulated a TU58 successfully in software? I searched
through the archives and found lots of posts that say "you could" and none
that say "I did". If it's doable, what software should I use? I found this:
http://www.ibiblio.org/pub/academic/computer-science/history/pdp-11/utils/t…
Second, where do I get the diagnostics to load over the emulated TU58?

I have over 100 manuals for HP's 16 bit series. Most have been scanned

Unfortunately, with the exception of the FE handbooks, HP tended to put

Look here:

When you open the front panel of the HP1000F does it have a sticker inside

Those are the loader ROM part numbers. Take a look at the document

which you may have installed in your CPU. The document also describes how
to load and execute the loader ROMs.

Hi Tony,
Saw your posts on the net regarding HX-20's. I was wondering if you would
be able to give me a couple pointers. I picked a hx-20 up a few years ago,
and am now getting a chance to play with it. I have downloaded and read the
3 PDF's on Epson's site. I have not been able to find a copy of the BASIC
Tutorial.
I have a ROM installed in the _bottom_ of the unit. Not in the expansion
slot, which is filled with the Cassette Unit.
Should the ROM be autodetected, or does it have to be loaded?
If loaded, how to I load it?
I have not been able to get things working experimenting with LOAD "PAC0"
and "LOAD PAC1".
When I first powered the HX-20 up years ago, it had a 3rd option, but then
I initialized it and of course, it is now gone.
Thanks in advance.

Wow! You guys are good. Maybe you can help me. I need some Fujitsu chip

I got them from Fujitsu, Hillsboro, OR, when they were discontinuing the 14" &

but am not sure. Fujitsu made quite a few products there, POS stuff too.
Thanks for the help.

thinking back some 18-20 years, you are right on this comment that the -YA -Yb
-YF variationd appley to the M9301 only, that module has no easy upgradable
proms, but standard multiboot configurations.
The keydifference is that M9312 stores one PDP11 instruction in 4 consecutive
nibbles of the prom, therefoere 1 Prom = 1 Bootdevice.
The 9301 has a conventional structure where the 4 proms are placed adjacent and
each prom provides 4 bits of the program. Therefore if you modify the 9301, all
4 proms must be changed at the same time. I had to do it once, adding a new
device to the boot routine, splitting it into the roms, burn those and get it
to work, and I remember it was a tedious job.

I just put up three docs at www.spies.com/aek/pdf/univac/univac3 that

One of the reasons it wasn't very popular was they didn't maintain backwards

Hello Gene,
Even though RD-5x fit in there fine, what is probably an inexpensive
but more reliable solution than the RD-5x is to go with 5.25" FH
ESDI drives as some other "personal users" have done. They
come in larger storage capacities than the RD-5x drives too.
Pick up a Sigma SCD-RQD11/EC when it shows up on eBay
for around $35 to $50 ( or even less these days? ), and ask
Mark Green about an ESDI drive. He got all four ( some of them
around 600 Mb ) that I had a couple of years ago for what would
have averaged out to $10 each ( plus shipping ).

A friend of mine is getting heavily into building radios, digital clocks
(using nixie tubes and/or miniature vector displays), etc. from tubes.
I've been thinking that some of those nifty prototyping boards like we
used in high school would be great for him to use for testing new designs.
The ones I used had a base made of clear plastic with an array of
holes in the top which lead in sets of 5 or so to a common set of metal
contacts. There were dozens of sets of contacts on each board. The tubes
were mounted in sockets on small squares of PC board with traces leading
to pins along the edges. These pins would plug into holes on the base,
and you would plug wires into the other holes on the same contact strip to
connect something to that pin. There were also inductors, variable caps,
pots, etc. on small boards. Any idea where I might be able to buy
something like this setup these days?

Howdy folks;
I'm trying to identify a Motorola chip for my father - his guess is a 300
baud modem...
The chip comes from circuitry which allows folks to remotely control the
lights on a runway. All of the breakers/generators are in a little shed at
the end of the runway, but there is a controller board in the tower to
allow you to turn on lights without having to trek down to the shed...
Unfortunately said controller is broken, and my old man has tracked it
down to this chip.
Any help would be greatly appreciated; Particularly since the people that
own the property have sold off the end of the strip to a local farmer who
keeps cows there... And the other pilots are a bit too soft to leap the
fence and wander through a herd of cattle in the middle of the night just
to turn on the lamps...

Yes, that's the item but I'm pretty certain that he's wrong about it being a field engineer's test set. A couple of list members have tracked down several of these but no docs yet.

Hi Joe

Well, my 11/34C has the M9312 in it.
See www.pdp-11.nl and click on the folder PDP-11/34A.
Inside that folder is a folder called CPU information,
in there is the folder options, and the last item is the
document "bootstrap" (M9312). Maybe that's a little help.
I have a scan of the M9312 manual and also of the M9301
manual wich will be at Jay's in a few weeks ...

Gene,
I took a look at the CTP dealer listing index, and the current listed prices
for UC08's run from a low of $300 to a high of $750 Out of the 12 listed
that have prices showing, the average is $511.25
There was a UC07 recently on eBay in the UK that sold for GBP 252.00
(currently approx. US $397.91 )
EMULEX UCO7 Q-BUS SCSI CONTROLLER FOR DEC
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1247&item=2307510324
With variations in exchange rate, that US equivalent was about $420 on the
day it closed.

Hello,
I just received this inquiry from a "personal use" user about a card
that I am not familiar with. If any of you want to help him out, his
address is included.
Wasn't someone asking about a differential scsi controller lately?
If he'd have better use for a single-ended, and someone else needed
a differential, perhaps you'd have a trade.

Subject: QTD-1 qbus diff scsi board - you folks know anything about???
Since you folks deal in legacy qbus things, I was wondering
if you might know anything about a Transitional Technology,
Inc., model QTD-1 differential mscp/tmscp scsi controller?
I have one that a friend sent me, to use in an MVII machine,
but I can't seem to find out any information anywhere about
the board. It is dated 1989, but must have been made by
one of the lesser qbus card manufacturers.
If you know anything about this particular board, I would be
most interested in finding out the particulars, so I can get
this thing running.
Thanks

I would like to do a bad sector scan on a RD52 connected to a RQDX1

When next I find myself looking at the bizarre heat sink and fan

Oh Man! I forgot ALL about that...
I found it wasn't the pins themselves, it was the
plastic hinges in the doors.
A friend used to keep the broken ones after we'd
replace them (I worked for a company that serviced
these drives.. Cleaned, re-aligned, repaired.
refurbished them...), and refurbish them for his
personal drives with metal hinges.

I must have somewhere all sorts of patched OS'es for
my old Model I. DoubleDOS, TrsDOS, NewDOS 2.1,
NewDOS/80, LDOS, VTOS, DosPLUS, the list goes on and
on...
I used NewDOS/80 for most things, followed by
Multi-DOS.
I have here a Percom flippy drive. It was a Wangtek
mechanism (I think) that had write protect, and sector
hole sensors on both sides of the drive, so you could
write to both sides of a disk without punching holes.
I got rather good at that, and used to sell home-made
kits for people to punch their own disks. As well as
installing Electric Pencil Lowercase Mods into Model I
Keyboards.
Micros back then were more like cars. You could
customize them heavily. Only now with all these
case-mods and cooling options are we getting back into
what used to be fun about being a Computer Hobbyist.
All things come around in a circle I guess...
My Model I was stolen from my apt twice, and I
recovered it twice because it was instantly
recognizable as mine. A local Model I guru knew my
machine and when it came in to him for service by the
kid who bought it out of the trunk of a car, he called
me and the police.
The kid complained he was out his $100.00 and wanted
it back from me. But, I felt... You buy stolen
equipment, you take your chances...
I didn't press charges when I got the machine back
though.
The first time it was stolen, the guy realized that
nobody would buy it from him, it was so custom.. So he
tried to ransom it back to me.
I said sure...
His ransom payment was me, and 5 friends with baseball
bats.
The police were stunned that I recovered the system
twice.
Those REALLY were the days...
*sigh!*
Regards,
Al
P.S.: though not booted in several years, my Model I
(which just turned 24 yo) is sitting a foot away from
me on a desk. I should hook it all up and give it a
boot for old times sake.

I also always wondered about this, and never found any clues. But don't bother,
its not very important. Those variation-codes just describe the situation of
the module at the time the first customer took them from the box, soon as you
change a prom or switch, its something else...
So just run the 9312 diagnostic from XXDP, it will print a nice summary for you
how the unit is momentarely configured and what its capabilities are. It will
also certify correct operation of your M9312 on top of that.
I hope you can boot anything else, do you have a DL11-W? You could use this
with a PeeCee emulated TU58 for diagnostics ect. If you need the Boot-prom for
TU58 write me off-list.

That depends on the physical socket-location where the 756A9 is plugged into.
Alternatively, you could use 773000 that will give you console-odt from where
you can interactively select the boot you desire.
Hope you get it to work,

Sellam,
You have it reversed again...
The only reason Cuba has economic sanctions is because
Castro refuses to step down, and allow the Democratic
Government that his people want.
Also, that Cuba supports and funds a lot of South
American Terrorism.
Just like Iraq, it is totally in Castro's power to
make life better for his people. Just step down and
let them vote for a new leader.
Again, you blame police for the crime, rather than the
criminals.

I would agree with that, but this isn't one of them.
Personally, I would like to see the sanctions lifted
as they don't seem to make a difference to Castro. He
is determined to stay in power anyway.
The only good thing is he will probably be too sick to
lead, or dead within 10 years, and probably at that
point the sanctions will be lifted.
A lot of mistakes were made in the U.S.'s policies
towards Cuba. And its' handling of the situation. No
doubt about that.
But hindsight is ALWAYS 20/20.

Based on the off-list conversation we had, it's much
more likely you decided not to listen to the proof...
I've never said the the U.S.A. should make the rules.
But, how can you quibble with the concept that it's
wrong for a county to attack it's neighbors, or to
build up offensive weapons?
Or, to defy the United Nations when they order you to
disarm?
The only way the U.S. figures into all of this, is
that it has the backbone that the U.N. does not have.
The backbone to back up it's own resolutions.
It's the same in international affairs, personal
affairs and in raising children...
When you make a threat, or set a condition upon
behavior, you have to follow through with the penalty
when the wrong behavior happens. Otherwise, you teach
that person (and others) that rules, threats and
responsibility are meaningless...
Nobody wants war, but in case such as this... This war
will prevent the deaths of millions. Not only by Iraq
and Hussein, but by others in the future who will take
this example to embolden themselves to do evil without
fear of retribution.
The penalty for breaking laws and rules must be swift
and predictable. That's the only way for there to be a
deterrent.
Saddam Hussein can avoid the war in a minute. He
simply can abide by the U.N. agreements, disarm
himself of the illegal weapons and technology, and
dedicate himself to making a good life for his
countrie's citizens.
He would have the added benefit of having the embargo
for sale of his oil lifted upon full compliance and
good behavior.
It's much more in his interest to do that, than the
course that he has chosen.
How can anyone disagree that what he is doing is sheer
madness? The guy can't live without fear of
assasination...
His life must be desperate and awful. And all by his
own choice...
Putting attention on the U.S. or President Bush is
wrong. That's focusing on the wrong end of the
situation.
Why aren't there protests calling for all police
forces to be disbanded? Using the same arguments that
people are using against this war, if the police
didn't carry guns or shoot criminals committing acts
of crime, why... There'd be a lot less death in the
world.
Just let the criminals alone....
In fact, how wonderful would it be for all the prisons
to be empty, and the courts to have nothing to do...
It's all the fault of those crazy police who capture
criminals for the fun of it. Because they LOVE to
shoot and hurt people...

If your religious beliefs contradict:

- Honor your parents
- Take a day off to rest
Then, I'm glad I'm not a member of that religion...

I didn't say it SHOULD be. I said IT IS...
Ask anyone who has studied law. Most of today's laws
are based on the 10 Commandments, The Golden Rule and
the Laws of Hammurabi.
The basic concepts carry, even if the details are
different.
If you bothered to actually read my message, rather
than be "offended" by it. You'd have understood that.
I don't claim to be the creator of that concept. I
read it somewhere, and found that I agreed with it.
The 10 Commandments are acutally pretty religion
neutral as most religions have similar "laws" and that
particular set is share between Judaism, Christianity
and several other derivative religious faiths.
But, please be offended by the thought that good ideas
are universal. Or that just because one faith brought
up an idea that it belongs ONLY to that faith and not
to other faiths, or even in the secular world.
So silly.
Good ideas, are good ideas. No matter who created
them.

Being that you haven't read said reply, you can't

you stoop to personal attacks rather than discuss the

Personal attack.
And what contradiction.
When has the U.S. attacked it's neighbor?
Last I heard Canada and Mexico are unmolested. And
before you bring up stuff that's 100's of years old,
you can't address stuff that old with todays mores.
Iraq attacked it's neighbors in modern times, with
modern weapons.
> This is typical of the mindset of control freaks:

Personal Attack yet again.
Do you understand a basic concept?
It's called "Being one's word".
When Iraq AGREED to disarm, to not own or develop
weapons of mass destruction, and then broke those
agreements. That's where the problem lies.
It's not about "control" or being a "control freak".
Adults make agreements and keep them.
That's the only way world affairs can work. Treaties
and agreements have to be kept, and there must be
trust that they will be.
When they are broken, they must be enforced. Otherwise
the entire house of cards based on agreements and
"word" collapses.
That leads to chaos.

None that I can see.
You'd like there to be one, so that you can attack me
personally.
It's a common tactic of people who are unable to have
intelligent discussions of issues.
Instead of discussing the issue or facts, and keeping
the discussion on that level. You attack the person
directly.
I could be the world's worst idiot. But, if I was
speaking a truth... What difference does that make?
I could be a drooling idiot and point up and burble
"Sky.. Blue..."
The fact that I could be an idiot, doesn't change the
fact that sky is indeed blue.
So keep the discussion on the facts, rather than
making personal attacks. When you do this, you rob
yourself of any power, and ability to have your
opinions considered and respected, and convince people
that they must be indeed, invalid since you needed to
make a personal attack.

I got news for you. Our President is not doing ANY
"ill pursuits". He has the highest sustained approval
rating of ANY President in history.
He is doing the right thing most of the time.

No. He surrendered to us in a war. He has made
agreements with our Government AND the U.N. that he is

He attacked two of our allies, was defeated and he

He is not doing that, and that makes it our business.
Sticking our heads in the sand (or up a bodily

problem go away, and emboldens others to break
agreements or to attack their neighbors without fear
of reprisals.

Not at all.
I would recommend you go to college, take some World
History and Civics courses. Also Ethics.
You hold some naive opinions. That sound good on the
face, but don't hold up under rigorous scruitiny.
They only seem good on the face, but when you extend
the consequences of what you would like to see happen
out on a timeline, you see that they don't actually
bring about the things you claim to stand for.
"Peace at any cost" is a misused statement. Often, the
price of peace IS war. Perhaps it wouldn't seem so
contradictory if you consider that in this context...
"An ounce of prevention is worth a pound of cure..."
If there were some science fictional way to look at
alternate timelines where we could see the different
outcomes for different decisions, perhaps there'd be
some data for you that might convince you of this.
Having this stand that I hold, takes some faith. It
takes trust that there are things that never happened
that we will never hear about, because they were
deterred.
If every country or terrorist made a press release
saying...
"I was going to do X, but didn't do it because I was
afraid that the U.N., the U.S., the U.K., etc... Would
punish me for doing it..."
Then, you'd see how well deterrence works.
There was an article in Time Magazine (or it may have
been Newsweek) fairly recently that said, that when
the U.S. pulled out of Vietnam, it emboldened all
sorts of actions.
Within three years of the pull-out, American Embassies
were attacked, Cuba stepped up it's actions in South
America, and more.
Backing down has consequences.
It's a tough row to hoe, and not as simplistic as you
make it.

Does anyone on here know anything about a digital computer demostrator unit made by IBM in the late '50s? It's housed in a nice wooden box about 2 feet wide x 15" deep x 12" tall. On the top of the box is a brass plaque that says "Presented by International Business Machine Corporation". Inside is a grey painted metal box with a row of ten 9-pin tube sockets along the back of top. In front of each socket is a single nean light. In front of that are blocks with small holes for jumper wires similar to those used in the Heathkit trainers. One end of the box has a male Jones plug connector and the other end has a female connector. It looks like the units were made so that additional units could be stacked together. On the front side of the grey box is a tag about 1 1/2" x 3" that says IBM in large letters. In a compartment on the right side of the wood case is a power cable that plugs into one of the Jones plug connectors. Under the grey metal chassis is a compartment with jumper wires, spare neon lamps and other small parts. Along the front edge of the box are two rows of holes that hold modules that plug into the sockets in the metal chassis. Each module is an open chassis about an inch square and 4 to 7 inches tall. Each chassis has at least one vacuum tube in it and some have two tubes, one above the other. Each chassis has a metal hoop or bail that goes up and over the top of the top most tube and back down the other side to form a handle for inserting and removing the chassis. On the top of the bail is a small tag with numbers like "TR-2", etc. Besides the tubes the chassis also have other small components such as resistors and capcitors. There are a total of twenty of the small chassis and each one can be plugged into any of the sockets in the main unit but you have to set a number of jumpers on each socket to a get the correct voltages for each of the tube elements. The tubes can be configured as logic elemements such buffers, invertors, various gates, etc and they jumpered together to form more complex d
e
such as flip flops. Evidently the nean lamps are used to indicate the state of each logic element. The guy that had it was quite specific and said that is is NOT an analog computer but a digital one. I went through it trying to find a model number or date but could only find the number 56 stamped on some of the tubes. I'm not sure if that's the manufacturering date or not but it's probably close.
Can anyone tell me more about this thing or even (HOPEFULLY) have a manual for it?
PS this came from the University of Florida.

Hi,
I got a strange board in recentley. Made by DEC, Quad-heigh, Dual-width, only
one double sided 2x18 pin edge-connector that is snmaller as usual, aperantley
carrying only power-supply connections. Has some 80 SSI/MSI TTL-chips, one prom
19-10818-02, and 10pcs 93l422 256kx4 ram's. Chips have 1979 date codes.
The strange thing about this board is, that there is hardley any external
connections, there is 1 (one) split-lug terminal, and one 16 pole IC-socket, as
normalley used for automated testing signal connection.
On the solderside there is the wording: "Waveform Generator" and 5012514F-P1
Who knows what this board is, and what it does? In what equipment was it used?
How and for what purpose are the 10 Mbit of RAM filled with what kind of data?
Fieldguide says:
M7071 U Video Display Sys: image memory, RAMs & buffer logic.
I don't understand this, because ther is no unibus-connection on this module at
all. Is it a part of something bigger?
Thanks,
Frank

All of Bush's decisions consider how it impacts the price of oil, and how
much money his friends will make.
I have heard Administration Spokespeople say that the Iraqi oil will
reimburse the US for the cost of the war. How else does he expect to pay for
the war when he is running deficits.
It is all about Oil and how much money the oil industry can make before the
resources run out.
Bush's goal is to make as much money for his oil friends as possible. What do
you think the current run up in prices is?
This is also why he is gutting environmental protections and ignoring global
warming.
This is why you can buy vehicles with the worst MPG and get tax credits.
It is all about OIL. If you view each of Bush's actions through an oil filter
it make them quite understandable. Bush and his friends are Oilmen.

I always preferred Tandon TM-100 drives. They needed a
lot less service and maintenance than the SA400's did.
And I always liked having the extra 5 tracks.
I've seen a few of these pop up on E-Bay.
Unless you have one for him, or someone on the list...
eBay may be his best bet.
I have 4 40 Track DSDD 360k PC Drives mounted in an
old PC Compatible case (XT style), that has a LONG
cable coming out the back. I use this for both my Coco
and my Model I (when it was working, my EI is shot and
while I have an LNW EI, I want a new KB unit as well).
The other thing about SA400 drives, is to make sure he
isn't using a patched version of TRSDOS or NewDos/80
or whatever...
If the stepping speed of the DOS is too fast, the
older drive may not boot properly.
I remember taking a copy of 80 Microcomputing and
applying the patches from it (with SuperZAP) to a copy
of TRS-DOS to make it 40 track, and to speed up the
drive step. The system booted up MUCH faster.
Boy, those were the days...

I'm sorry but none of the above is true.
Unlike the Clinton adminstration there is no spin
here.
It's all the truth, and policy based on hundreds of
years of human history observed.
You should be ashamed of resorting to trick of
comparing me, Bush or ANYONE to Nazi Germany, or
Germans (I am also of German descent, and proud of
that. Though not proud of Germany in the beginning
years of the 20th Century). It's just low.
Luckly, I don't take it personally because it's on the
same level (and as funny to me) as "Yo Momma!"
And I'm NOT in the minority. Given the approval rating
for the war, AND the President I'm in the majority.
Though Liberals would like Conservatives to think they

The truth is, that we're not.

Hello John
How are you. Sorry for late writing. I was out of
station for last couple of days only today I joined my

John I am unlucky I do not have the Kermit S/W in my

Is it necessary to load any communication S/W like
Kermit in the winchester disk, because I also can not
load any S/W in my winchester disk. Now I think I am
in trouble.
Fortunately I also have VanDyke's CRT404 with me & I
can load this in my WINnt PC.

Hi All,
Today I spent driving up and down to a place that had a bunch of
interesting stuff for me. Amongst others, some VAX 4000 stuff, a
truckload of DSSI disks, and: some StorageWorks stuff.
The haul included two HSCZ40C controller cabs, cables, and several
(empty) BA356-JC storage cabs. I still have a bunch of RZ28's in
their SW trays, so plugged them in, for fun.
Everything seems to be alive, I could use some docs on this,
though.. esp. the HSZ40C controller, which obviously needs to be
configured through its [unknown pinout] serial port...
Thx,
Fred

One last riposte for these supposed "patriots".
FEMA was brought in by the Reagan-Bush administrations and
now Junior has extended the rights to suspend the rights
enshrined in the US constitution by the founding fathers who
could never have imagined the rapacity of the present bandits.
Check out
http://www.sonic.net/sentinel/gvcon6.html
or if you want a real example of the big sell even extended to your
kids
www.fema.gov/kids/
But of course there is no brainwashing going on in the US of
The New World Order.
Or if you are even capable of reading something other than
spin-doctored news-clips, read " The Praetorian Guard" by
John Stockwell, the highest-ranking CIA officer ever to quit the
agency and expose the truth of it's operations to Congressional
investigators, if the book hasn't been "disappeared" by the
State Department. You might even re-examine the positions of
the "discredited" former US Attorney-General Ramsey Clarke.
Enough of this BS, I'd rather ignore the parroting rabble and go
back to figuring out the workings of "non-computer" micros and
even "non-computer" DEC micros. I shut ma mouth...

I received my EMC2 Orion SSD today... I have to say I'm impressed, it
definately is what we'd considering "Enterprise" these days...
The unit is, according to its manuals, 31.4" x 33.3" x 11.5", and weighs
roughly 275lbs.
The Orion has some nine slots in what looks like (but isn't) a full-size
3-connector VME bus cardcage. It has one "Director" (controller) card, and
five 64MB memory cards installed (320MB). In the rear of the unit is one
Maxtor 320MB SCSI disk, for offline backup, and two sealed lead-acid
batteries (So that in an emergency power off situation the unit can back
itself up to the internal SCSI disk and not lose data).
Pictures are available:
http://www.kiwigeek.com/hjp/comps/emc2_orion.html
Now all I need is an IBM that can read from a IBM 3370/3380 DASD - which
is what the Orion emulates...

Because none of those countries attacked three of it's
neighbors using them, were forcibly expelled from a
neigboring country and agreed to disarm as part of the
surrender agreement.
We have not picked Iraq out a hat to disarm them.
They asked to be disarmed when they used their weapons
against their neighbors AND their own people (Northern
Kurds).

Did you not listen to the same presentation of Hans
Blix that I did?
He stated that not only did they find things, they
found more things than Iraq reported. They found Iraq
had developed weapons with a greater range, and in
amounts in excess of the agreements.
What is stunning for any intelligent person, is that
he then followed that by saying he saw no problem with
Iraq and that they were following the agreement.
He basically said they WEREN'T in compliance, but that
is was not a problem for him.

There was such a thing, vis-a-vis Iraq. It was called
the Invasion of Kuwait and the bombing of Israel with
Scud missiles...
What is happening now is of a piece with that. When we
booted them out of Kuwait, they agreed to disarm as
part of the surrender. They have not been keeping
their word.
They are in breach of their obligations, AND have been
continuing to develop illegal weapons.

All,
While rewiring the VAX Lab here, I found something weird is going
on with the power usage on the network.
First, some stats:
UPS 1: 2400VA, mains load 220VAC (Compaq)
UPS 2: 2200VA, mains load 220VAC (APC)
All power is 220VAC, 50Hz, single phase. Regular European power,
so to speak. No weirdness there. The Compaq UPS is connected to
the Compaq servers and related (MicroWalt Corp) equipment. This
is the PROD network.
The APC (new in town) is for the VAX stuff and related equipment,
and powers all of that. For now, an 4100, a 3100 and some hub/
router/DECserver et al equipment.
Here comes the fun part. All this *used* to be on the Compaq UPS,
and it was fine, just at 96% of its load.
Now that things are split out... the compaq screams even *more* at
me, even though its reported load is ~1650VA.
My real question:
These UPSes have 3 load segments each. On the Compaq, I currently
use *2*. Is this the reason for its screaming? Does the total
load come from the three segments?
Call me stupid, this I cant figure it out. I probably should not be
doing this at 4am :)

What's great about people like you Sellam, is that
every time you think something like this, you get to
have egg on your face when it turns out wonderful.
I remember all the doom and gloom and naysayers, and
the predictions of thousands of bodybags for the
Afghanistan War on Terrorism a year and half ago.
People thought that those in favor of that were dumb
too...
I am not someone who loves war. But, I am someone who
believes in backing up rules, laws, and civilization
with penalties when the rules are broken or in the
case of Hussein, not only broken but flouted.
It will be over fairly quickly once it starts, and as
before (in 1981) it will be a rout.
But, this time we will take Hussein out of power and
set the people in Iraq free. Iran is probably next on
the President's list, and then North Korea. Unless Kim
Jong Il pushes to be the next in line and won't wait
his turn.
It's so wasteful for people like Hussein, Il and the
leadership in Iran to do the kind of things that cause
this, rather than dedicating themselves to providing
the best possible lives and economy for their people.
Since we still have people here in the U.S. who think
ideaology is more important than doing the right
thing, I'm not surprised there are similar people
elsewhere...
I hope the human race outgrows that someday...
It's ok for you to think people in favor of taking
Hussein out are stupid.... It only means you don't
have a clue what it's all about...
Hopefully getting egg on your face a few more times
will make you tired of being wrong...

We were genuinely worried about Castro's wanting to have nukes only
90 miles offshore of the US mainland. Right or wrong, it was a real danger
we wanted not to have happen.

That's fine, but you still haven't provided the

That's like asking for a drive and cable for an Apple
Computer...
Please be more specific, and I'm sure there are lots
of people on this list who could be of help to you.
To repeast someone else's request:
- What kind of TRS-80 is it?
- Do you need an internal or external drive (i.e.: a
Model III or IV can use both)
- Do you need a case and power supply?
- Do you need a 35 or 40 track drive? Or do you need
an 80 Track Drive (mostly determined by the model, and
the type of disks you want to read).
If you can be more specific, those of us willing can
be of more help..
Thanks!

Hi Bruce:
When you say that the telex machines used a "high-voltage DC, 60mA current
loop," is that implying a 120V loop as in standard TTYs? The reason I ask
is that the "private-wire" current loop for an M32/33 is a max of something
like 45 volts on the loop supply. I presume then, that the telex interface
box was designed for the HV, 60-mil telex loop, and then in turn drove the
internal 20-mil input to the selector-magnet-driver card of the M32. Was
this telex interface box in the M32 stand?
I had not heard of later M32s having Telex Line Adapters for FSK modem
application. How can you identify which interface an M32 has? Was there a
different dialer CCU, like the one with six pushbuttons used on the twx 33s?
I have some additional telex info from other folks added below.
ps: Bruce, did you see the post about all those TTY machines for free in
Seattle? Lots of good stuff headed for the dump.

-------------------------------------------------
More telex info from George Hutchison:
Using a Teletype Corporation equipped telex machine on RTTY is relatively
easy.
You need a loop supply with a current limiting resistor (2K or so
wirewound pot) a double-pole double-throw switch, and the telex machine.
Connect the DPDT switch in the standard manner for reversing polarity.
Feed the loop supply (Such as one would find in a 28 LESU) through the pot
to the center terminals of the switch.
Wire the reversing terminals of the switch to the telex machine input
cable/terminals.
If you plug the telex machine into 110 VAC, with the loop supply
de-energized, it will run open. Some folks tweek the dial on the telex a
bit to get the machine to lock up, but this is not necessary.
Energize the loop supply. Depending upon the position of the DPDT Switch,
the machine will either stop running open, remain on and be ready to type
uponst, or will shutdown and the motor will stop. Flipping the switch will
result in the opposite condition to occur. With the machine energized and
the loop locked, set the loop current for 60 ma.
When the machine is on and ready to type, it will key the loop that is
coming from the loop supply. From there it is easy to use it to key
another machine, a transmitter, or what have you.
When the machine is in the off condition, motor shutdown, etc, depressing
the "LOCAL" button on the telex will cause it to come to life so you can
type locally.
I have an ST-6 that I removed the 110VAC that goes through the motor
control relay, and set it up with the reversing arrangement as described.
Most ST-6 motor control relays were DPDT. The loop current from the ST-6
goes through the motor control/now reversing relay, so when the ST-6 says
turn on the motor, the loop current flips polarity and turns on the telex
machine. Such a deal.
Thought some of you might like this bit of info.

-------------------------------------------------
More telex info from Don Robert House:
I have always just used the loop rather than tapping into the SMD
circuitry. I set a loop supply of 120-130 vdc to 62.5 milliamps with
two machines wired in series into the loop. The machines usually
have a mounting cord on them for this purpose.
The M32, if it is a former Telex, it uses the ITA2 version of Baudot
code. It is a 7.00 unit code with 1 start bit and 1 stop bit, which
is 50 baud and 67 words per minute.
-------------------------------------------------
More telex info from Jim Haynes:
There are two Telex interfaces to the M32. One is neutral, and the
other is a polar adapter that plugs into the neutral one.
Look in the Western Union Technical Review CD ROM; I think it's all
documented in there.
And yes, it's 50 baud, 7.5 unit code.
-------------------------------------------------
More telex info from Wayne LeTourneau:
Most Telex's are 66 WPM, I have 60WPM gears in mine and I connect the local
loop to terminals 8 & 9 in the rear. Local loop set at 60ma and not to
exceed 100 VDC.
It copies fine, I'M using a Flesher 170 tu. It also has automatic caridge
return and automatic line feed, so can copy those RTTY stations that are
using computers and don't have enough sense to send a LF and CR at the
right time.
I cannot get mine to talk to itself yet, have not figured out how to get
the keyboard in series with the printer.
Actually, the selector Magnets on thease draw close to 500ma, so you have
to use the driver card, which is where terminals 8 & 9 end up.

Wow !
Tony, could you send some photos of your disk drive ?
I'd like to see this "mystical" thing ! :)
The 24" platters of IBM's RAMAC are known to me but 36" platters ???
Who could have built such disk drives ? Any ideas of the company ?

I just received a new board set for my VAX 11/750, which includes
an L0004 to replace the one I had before, which would send output
to the console, but wouldn't read input from the console. Now, however,
when I put in the new L0004, it prints garbage on the console. What's
more,
the _old_ L0004 doesn't print anything on the console anymore. Any
ideas?
TIA,

Hi, I have just bought a nice clean TELEX machine, it's a TTY-32, 5-level
coding,
with what looks like a phone line hookup, dial-type phone.
I wonder if anybody knows what the modem standard is for this, and/or any
phone number I could call to test this thingy out!
Thanks,
George
Patrick -
I dug out my Votrax manual (1982), and can give you the voltages:
Pins 1-3, 26 VAC, 180 ma
Pin 2, 20 VDC, 50 ma
Pin 4 is 0 volt reference
Unfortunately I don't have a PS for mine either.
Be careful if you find a PS from the Votrax Type 'N Talk. It also has the 5
pin DIN, but it puts out:
Pins 2-4, 19.8 VDC, .35A
Pins 1-3, 17.0 VAC, 1.0A
I do have a working TNT, and it is cool!
Also, the DIP switch configuration on the PSS: (1 is up, 0 is down)
1-3 baud rate: 000 - 9600
100 - 4800
010 - 2400
110 - 1200
001 - 600
101 - 300
011 - 150
111 - 75
4 up - xon/xoff for serial port
4 down - rts
5 - unused
6 up - power-up message spoken
6 down - power-up message not spoken
7 up - parallel port used as input port
7 down - serial port used as input port
8 up - self-test - continuously performs diagnostic test - no access to PSS
in this mode
8 down -normal operating condition

Hey,
Here's one for the Military members, and taxpayers, of the list ...
>from the "serial killer", "dick", "genital lice" that we are here in
Virginia ...
The Navy recently needed some Ariel Hydra Plus DSP boards and
contacted me about them. They mentioned also searching eBay.
Well, I ended up seeing some at ...
Ariel Hydra VME single board DSP computer
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=162&item=2302043683
I talked to the seller and he thought he had a thousand dollar reserve on them.
I told him, no, no reserve, just $500 opening bid.
He had made a mistake listing it and ended the auction because of his mistake.
I couldn't buy them. My buying budget couldn't cover $1000 boards that I wasn't
sure were even going to be the right part ( minor difference in last digit
of part
number) and I'm not an extraordinarily strong player.
But I gave the client the seller's phone number, and seems they may have
had possibilities.
Response from client ...
> Bennett:
> Will do. The boards on Ebay do not have the VSB option that we ideally
require, however these boards still may > be workable. We are researching
to find out what the slightly different part number denotes. We are still
> interested in any additional leads you may be able to find. Thanks for
your work on this!
I still want to follow up and see if this worked out.
Wish I could have made a little to cover my bills, but didn't seem doable
on this one.
But I might have saved you all a lot of money, and might have solved a
national need.
Can't post client contact info though. Having anyone pestering my clients
would be a no no.
But, might have built up the karma level. Right now I might see the light
at the end
of the tunnel on a project for the Saudi government. ( They are our allies ).
Also just donated a chassis to Cornell University ...
http://wwwapps.ups.com/etracking/tracking.cgi?TypeOfInquiryNumber=T&Inquiry…
With chassis, you can't get enough for them to make them worth packaging
and shipping.
So my terms were the mailing center had to do it. Plus I didn't have
suitable materials.
Used to wish we could bring some of you with us, but you made it seem
better to go it alone.
Incidently, with the situation overseas, the US military and many defense
contractors
are currently re-evaluating their spares levels.
Best Regards
Mark, I followed your thread about troubleshooting your monitor. I have a
warehouse in Melbourne Florida with some good and probably some bad VT320's
on the shelves. If you zero in on a bad part or suspect something as bad and
would like to replace it send me an email and if I can pull one from a unit
here it's yours for the cost of shipping.
regards,
thom
hello,
I recently inherited an IBM 3151 terminal, but no keyboard! As some of you
may know, this terminal used a keyboard with an RJ-45 jack on it.
I have been able to find pinouts of both the terminal keyboard connector and a
regular AT style keyboard. I connected all the wires appropriatly, but no
go. The terminal still says "Problem in keyboard".
so, two questions.
1) is it even possible to use an AT or PS/2 keyboard with a 3151 terminal?
2) if so, how?
ps, I am not subscribed, so please cc to me.
thanks,
jason pepas

While U.S. Robotics did not invent the modem, they were one of the first
companies to sell them for home use. Here are some U.S. Robotics data sheets
that I got in February 1978.

I don't want to argue about who was first to sell a modem. I just think it
is neat that U.S. Robotics is still around and I have these data sheets
