I feel the IP is embedded in the instrument, not the manual. Thus
the manual provides a way to make use of the IP you've bought and
paid for in the instrument. It's the old instruments HP / Agilent
no longer supports that we're talking about here. The simple fact
is that there are *far* more instruments out there, than original
manuals, because when one goes surplus the company's file drawers
of manuals tend to get thrown away or otherwise lost, while the old
instrument exchanges hands a few times and finds a new home.

Plus there are manuals that disappear for who knows what reason.
The manuals for some HP equipment I purchased new when I came to

the
Institute 17 years ago somehow no longer exists at the Institute.
Did a postdoc carry it off with him in his files when he left? Did
it get thrown out by mistake? Who can say, but it's gone. And now
a copy is not available from Agilent, the product line having been
discontinued long ago... So I do rely on others who are willing to
make a copy to keep the IP in my instrument useful.

Thanks for taking the time to respond, Mr. Hill. I stand corrected --
there are far more "orphaned" old HP instruments out there than
original manuals. Your point is valid.

Maintaining an instrument document control system is relatively easy

in
a manufacturing facility with a limited number of engineering
personnel. It's certainly much more difficult in an academic
environment with dozens or even hundreds of students who all want
access to the instruments and their manuals, and don't have enough
experience with instruments to make educated guesses about how they
work.


That doesn't make sense. All the department has to do is hand over the
manuals to the library (this _is_ in an academic emvironment!) and let
them put the manuals in Reserve, where they can be checked out for a
very limited amount of time, say two hours, and not be taken from the
facility. The student can then peruse, or even copy them if he has a
pocketful of dimes. At least this is how we do it at the college where
I work. Actually, the student can now buy credits on a card to put in
the copier, so he doesn't even need coins to make copies. One can see
this big warning sign above the copier with legalese about copyright
restrictions etc. Mostly ignored. :-P

I agree that the value of the instrument is inherent in
the instrument itself, not the manual. But just the fact that we're
having this conversation indicates the documentation is of value,
although of another kind. It allows me to utilize the investment in
the instrument.


Everyone, including the legal system, should view certain types of
manuals as different than other IP. In the case of an instruction
manual, this is is directly related to the instrument, and has no real
use or value on its own. Therefor the owner of an instrument should
have the right to own this manual, no matter where or how it was
obtained. I would go as far as to say that the instrument maker should
be obligated to supply one to the owner upon proof of ownership, but the
makers wouldn't want to be stuck with that responsibility.

OTOH the repair, service, maintenance manuals are another case, and
since they might reveal something about the instrument that's not
notmally available to the owner, the owner wouldn't have any right to
these manuals.

One thought. Many of the test equipment (and manuals) were

duplicated
for the miltary. One off the top of my head is the AN/USM-81 which

was
the same as the Tek 541 'scope, IIRC. This may not be copyrighted,

or
may have some other way of getting around the copyright laws. And

many
schools, such as the military schools, published schematics to use

for
training.

Jeepers, I wish those military manuals were better. I downloaded a few
of them from https://www.logsa.army.mil/etms/online.htm and although
they were usefull, they certainly were not up to par when compared to
the real thing. Often unreadable schematics and missing vital info.


Well, the 'unreadable' and 'missing' sound to me like that's a copying
or scanning problem, not the fault of the manual itself.

Generally, when I was in the army, the manuals were broken down into 5
levels.

1 - operation (like how to drive a car)
2 - maintenance (like how to change the oil, add water to radiator,
etc.)
3 - service (like tires, batteries, etc.)
4 - field repair (like fixing the starter or the brakes)
5 - depot repair (like rebuilding the engine)

Those 5 "echelons" are only a rough idea of how the manuals were
arranged. Some military manuals were combined, such as a "-35" manual
included the 3rd thru 5th echelon - basically everything about service
and repair. A "-15" manual would be all of the above.

You may have to get 2 or more military manuals to get all the info that
might be in a regular equipment manual from the manufacturer.

If anyone has found a better place to download this stuff then I'd
love to see a follow up post about it.


Well, if you are in the military, I would imagine that all of that is
now online and available to the authorized people.

On a side note, it's my experience that there are not many folks out
there who really know how to maintain electronic records without
corruption and loss for more than a few years. I've seen data get
corrupt because folks do silly things like copy large repositories of
data from one place to another and then neglect to do a binary
compare, run disk defrag software against large drives containing
valuable data on machines with crappy systemic bit-error-rates,
transfer gigabytes of data on computers without ECC memory or
without UPS protection, no backup strategies or crappy media or
unmaintained tape drives. Failure to check C1/C2 error rates on
freshly burned CDROMS, and on and on. Many perils.


Welcome to the Real World. Bugs eat papers, manuals and books. Acid in
the paper makes it turn brittle and brown after a few decades, making it
nearly useless. But these problems are not related to the topic were
discussing. However the bookworms should be very concerned about the
copyright restrictions because they are severely restricting their food
source! ;-)

But I've had a bias against hp equipment for at least 30 years... a
whole lot of it was crap or became crap within one year. When I

ran the
Phoenix Analog Design Center for GenRad I forbade the purchase of

hp
'scopes.


But their scopes always took a back seat to Tek, so if they didn't

want to
flush money down the toilet, they would not have bothered to invest

the
money to make and sell a scope that was competetive with Tek.

However I used a HP 1741 back in '79, and I thought it was a solid

scope.
It was a blessing after rubbing my fingers raw from turning the

timebase
and other knobs 100's of times a day on a Tek toob scope. The HP

probably
saved the company tons of money on electric and air conditioning

costs by
getting rid of those old Tek toob scopes, which used a half a

kilowatt of
power all day long.


HP dumped their REALLY crap scopes on the military. The worst scope I
ever tried to use was an HP in a waterproof AGE[1] box. Not only did

it
have the legendary "can't trigger" problem that's endemic to HP

scopes,
but the waterproof knobs gave new meaning to the term "backlash."

But then again, the only thing I could honestly testify to re HP test
equipment is they never got the triggering as good as Tek. All of

their
other stuff was, as we all know, essentially perfect.


Aw, c'mon, Rich! We all know that perfect is a straight wire with gain,
with a bandwidth from DC to daylight. And we all know that even HP
couldn't do that. Nice try.

The check to purchase the third edition of a "certain universally
respected textbook of Electronics Engineering" mentioned above, of
course.

By the way, I bought the second edition used. I'd consider it an honor
to be able to cut a check for a new copy of the 3rd edition, so the
authors could directly see the benefit.

In business, the best way to say "thanks for the help" is in cash.
Which is kind of the point of this whole discussion, I suppose.

It's been too many years -- placing the manuals on reserve in the
Engineering Department library is an obvious idea. A smart instrument
manufacturer might also allow professors to make a copy for their
personal use or to chain down in the lab, where it's most useful.

If I buy a old used car which is no longer supported by the dealer
network (like a '67 Ford Mustang), I expect a set of keys from the
seller, not Ford. I wouldn't buy a car without them. I feel the
manuals are an integral part of the whole instrument package, and I
also feel that a manual should be sold with a used/obsolete instrument
if it was originally sold with that manual. Ideally, the seller of the
obsolete instrument should provide that manual, and buy it if he
doesn't have it.

Fact is, though, most sellers of old HP instruments don't provide the
manuals. That means we've got to scrounge them up. Agilent provides a
list of suggested vendors he

http://tinyurl.com/brg64

I ran down the eight web links listed on the above page looking for the
HP 5370B manual. ManualsPlus has it for $75.00 USD. Consolidated
Surplus (which is double-linked, there are actually only seven in the
list) shows available, price not listed. W.J. Ford Surplus Enterprises
shows Not Available but e-mail to be sure (too bad -- they rent manuals
for $10/month!). The others come up blank. Also, yesterday I made a
call to another vendor I occasionally use and found that he had it,
too. He wanted more than $75 for it, though.

To be honest, I think all of these arguments about how manufacturers
should provide more manuals for old, orphaned instruments, or broadcast
them free on the internet, would hold a lot more water if there weren't
any used, legal manuals out there.

humor
If I could be permitted an analogy. Let's look at the user manual "The
Joy of Sex" by Alex Comfort. The book is not sex. You don't need the
manual to engage in sex, or to experience joy in sex. The manual has
no intrinsic use for sex on its own, unless you happen to want to know
how to use your instrument better. However, Dr. Comfort's heirs (he
passed away a few years ago, I hear) would be most unhappy to hear
that, because of these admittedly true facts, you copied the manual.
They would, however, encourage you to engage in sex to your heart's
content, even if the instrument is old, and even if it is no longer
well-"supported". As I remember (it's been about 25 years (since I
*read the book*, Rich!) ), Dr. Comfort actually recommended that. :-P
/humor

I still think a lot of this discussion comes down to whether
electronics designers (who, after all, are being paid to create
intellectual property) are just trying to skate around the necessity of
paying for somebody else's intellectual property, which has admitted
value. Otherwise, why would we be having this discussion at all?

I understand everything that's been said about this by others, and
actually agree with a lot of it. I respect these opinions, and
everyone here has good arguments. But I'm not going to change my
opinion, because it's a matter of principle and the way I do business.
My employer or customer is paying for his pleasures. Period. If it's
copyrighted, the person who's paying will get a legal copy. There are
better ways to save a few bucks. And if I buy a used and non-supported
HP instrument (like the HP3456A), I'll spend $25 more for a legal
manual, even though I could find a copy. That's one of the joys of
being in business.

If the copyright laws need to be changed (and Frith knows they do),
then let's change 'em.

I've used CDRWIN to generate my 2353 byte raw images. This is
important to me because things like equipment manuals which contain
text can be kept heavily compressed, so if a single little error
creeps in, it can affect large portions of the text.

On the other hand, providing fee manuals encourages folks who are

vintage HP equipment on eBay for hobby use. This is a great way to
promote NEW EXPENSIVE HP product into the corporate environment. If
folks end up purchasing Keithley for hobby use just because they can

Unfortunately the restriction of documentation for obsolete equipment is
a profit motive by Agilent as it promotes the planned obsolescence of
older equipment which competes with new equipment on the market.

laboratory, directed to the relevant authorities at Agilent to
get the policy changed. It's dramatically counter-productive to
their own business interests, and it's manifestly unfair to the
owners of old HP / Agilent equipment who for one reason or another
no longer have an operating or service manual, and who cannot get
one from Agilent. For Agilent to close them off from a solution
to their problem is to render their bought and paid-for equipment
useless. It also means Agilent is capriciously denying the implied
warranty of merchantability for their older products; the product
can hardly do what it is supposed to do if the owner doesn't know
what button to push, or how to interpret the panel reading. And
it means Agilent is denying the owners' right to his own self-help
in repairing something he purchased fair and square. Moreover, it
takes a big step toward removing from the public weal the value of
old instruments, no longer manufactured, which in many cases are
not replaced by newer instruments performing the same function.

I've used CDRWIN to generate my 2353 byte raw images. This is
important to me because things like equipment manuals which contain
text can be kept heavily compressed, so if a single little error
creeps in, it can affect large portions of the text.

Compression used to be necessary when HDDs were under a GB, but not
anymore. Compress your .JPGs, .MPGs and .WAVs, but don't try to
compress something that doesn't take up much room to begin with. HDD
space is a half buck per GB, fer crying out loud! Use it! Instead of
compressing the data, get a bigger HDD!

I wish I could afford more space. I've got a 250GB drive in my server,
and then I have two more 250GB drives that I use for rotating backups.
Once a year I freeze the backup to DVD. What I need is four 250GB
drives in a RAID5 in my server, but then I have to buy more drives for
backup too. The price quickly becomes prohibitive, and I'm not even
taking the cost of a SATA RAID5 controller (3ware?) into account.

Ouch!

I sense I am getting flamed for some reason. I am not an apologist for
Agilent. In fact when I buy any substantial new equipment I insist on
getting full service manuals because of that very reason.

Wow. 1T byte. What are you storing, if I may ask?


Well, it's easy to fill a big drive up when you use computers in place
of your TV/VCR and Stereo, and when you scan everything in, digital
camera which takes movie clips, the wife and two kids, a home network
with 7 computers on it, and software for both windows and linux, a
full set of MAME ROMS and disk images, bla bla bla.

We have 37 terrabytes worth of x-rays, CT scans etc at the hospital
where I work, all online in spinning disk, so a measly 250GB at home
doesn't look like a lot in comparison. A few more years and we'll all
have terrabyte hard drives at home.

No. If the equipment makers have to sell newer equipment by making it
difficult for used equipment, instead of adding features and performance
to the newer equipment to make it sell itself, then they're just a bunch
of marketers and should be in the 'selling sugar water' business, as
Jobs once put it.

What about convenience Watson? I really *like* having everything
online and centrally accessible, instead of having to dig for it. Hey
I can even pull my stuff up at work and at other peoples homes. That's
really nice one-stop shopping! Plus if my house burns down or I get
robbed, then I can just restore a backup. I'm actually serious. It's
not that I'm just trying to get a rise out of you....

Naturally I disagree: Owners of hardware should be able to get the
service manuals for their purchased equipment. Some sellers want
to keep the repair profits for themselves, but in my opinion this
is unwise. OK, we'll leave that point.


When shopping for expensive lab equipment for my employer I've always made
the purchase dependent on the vendor's willingness to supply full
schematics. Not only for repair, but also for modifications that are
sometimes necessary for research use.

Some of our best STM data aquisition systems were purchased from a company
that was very hard-ass about releasing the schematics (a British company
named "WA", later aquired by Oxford Instruments). If it weren't for the
schematics that we forced them to turn over those systems would now be
useless. Ironically the company went out of business, whereas another one
in the same market that always ships equipment with full schematics
(Omicron) is still doing fine.

I disagree. If the instrument maker supplied an instruction manual
with the instrument when it was first sold, then, as far as I'm
concerned, he's under no obligation to provide further _free_ copies
of that documentation. As a courtesy, it might be nice for them to do
so, but why should they _have_ to?


I don't think they should _have_ to, but at least they should refrain from
enforcing copyrights on the manuals (i.e., keeping customers from sharing
copies).

Bad marketing. I at least am much more likely to purchase some new
equipment from company X if I know that they are actively or passively
supporting out-of-date equipment.

Lynx Robotics, for example, is such a company: Although they have long ago
shifted their line of business to something else, you can still download
the old DOS software for their motion control equipment made in the 80's
from their website. For free, without registration. In my eyes, as a
potential customer, that makes them _very_ attractive.

I can't even access that website.


The military is screening IP addresses, trying to match them to
geographic locations, and blocking access from outside the US.

The screening isn't perfect, BTW. Sometimes real USAians cannot get to
it, sometimes foreigners can...

Not accessible form outside the US of A, I believe.

A real pity. It appears I have misplaced the PDF file with the service
manual of my HP3466A multi-meter.
