Only the group's owners can sort it out, and of course they are far too busy.
Nobody else has the necessary permissions, except the people who uploaded the
original data in each case.

You don't seem to know much about how these groups actually work.
I'm smiling, but there are undoubtedly a number of members of this group who are
also members of the other group I alluded to, who know what I've been doing over
there for the last year or so, and who are laughing like hell at you right now for that
bellicose declaration.

No, you don't need to be a group owner to manage files. You just need "moderator"
status and you can push the files around all you want. Any one of the nearly 7000
of you could do it... if anyone cared to, and the group owner(s) trusted you.

Parting Out 7912AD

I have a complete 7912AD with a trashed scan converter tube (damaged in
shipping). Since it weighs a ton and does nothing useful, it's probably
best off as a donor for someone's project. Please send your requests for
any boards/assemblies offline.

And given the existence of the search function, a neat hierarchy of directories isn't actually required. Taxonomy is basically redundant these days,

As suggested above, whether the group under consideration is/becomes
"moribund" (by whatever definition) or not is immaterial. To me, what matters
is that there's a findable, coherent archive of resources needed for making
use of [obsolete] digital development and debug tools of *all* makes. I submit
that a contributing factor in yours becoming comatose is that it was Tek-specific.

If you were a marketing guy, you would see that bit of data, and
discourage the suits from wasting resources on a logic analyzer
group.

As I said earlier, John and I started Tektronix-Logic-Analysers,
must have been 10 years ago, and we just got our first new member
yesterday. And a new post too, asking if we should do something
with the group.

I think you have answered your own question:

There really is little interest in a tektronix logic analyzer group.

Don't believe me? Start your own on groups.io. It is free, takes
less than 5 minutes, and you too can own your own moribund group!

In analog equipment, yes. But my quick search of the terms "TLA", "DAS", "510", "520"
and "9200" in the files section turned up NOTHING relevant to Tek analyzers.

So what is there to split?

I quite agree on all of your points. But see my previous post: When it comes
to logic analyzers, it appears there's little or nothing to split.

You funny guy. We eat you last.

Problem (for me) is that there's some truth in what you said... but I have to keep those
tendencies under control or I'd get *nothing* else done. And with summer around here
lasting about 15 minutes, I have far too much to do outside.

But come winter...

It is highly unlikely that will ever be the case with a group for "obsolete" test equipment! (No, I don't read every post, but I do see the subject of every post)

One other comment, if I may: I just took a look at the files section here, and can there be a

Egge:

*Finally* the right answer! Thank you very much, and the price on these is right, so I'm stocking up.

All:

As David pointed out, what started as a small question kind of exploded, so I'd like to reorient it for
just a moment. Whether there's a need for a *discussion* forum is open to endless (and, probably,
increasingly tedious) debate, and the conversations will (it's reasonable to speculate) range across
a spectrum between "tool itself" and "application", I think we can agree. 'Nuff said on that point.

So perhaps I should have been a little clearer: My experience in the other group I alluded to (which
I share with David) is that the forum proper isn't enough; to a very large extent it's about the "files"
section, which has become its centerpiece. We've amassed a considerable archive of the user
manuals, software, firmware images, and schematics necessary not only for using and maintaining,
but augmenting those systems. Users are replicating (otherwise-unavailable or expensive) component
modules thanks to the collective effort to gather documentation *and* reverse-engineer.

While I'm not suggesting anyone's going to go *that* far wrt analyzers, if you pick something up at
a smokin' deal (dead or alive) and want to get some use out of it, there oughta be a central repository
for all its related material. No manuals? Got 'em. Bad firmware? Download an image and burn your
own replacements - and maybe upgrade to latest rev while you're at it. And the reason to make it
general (rather than manufacturer-specific) is that (to the best of my knowledge, at least) the previous
efforts to create and/or sustain an exclusive group (in this case *Tek* analyzers) have flopped or stalled.

So let's go another way. We can toe-chew the usefulness of such a group endlessly, but it's going to
be more informative to actually *try* and see what happens.

Hi jslcanuck,

Regarding your search for KlipChip Interfaces you can use P6417 and P6418 Accessoires (PN:196-3431-00 and 196-3432-00). Even the P6417 8-Channel Podlet Holder is a Black Version of the older Grey Coloured 92A96/92C96 Podlet Holder. Older 196-3431-00 and 196-3432-00's have no label and the cost savings are substantial.

Fair enough (it is $330 retail I think). I just looked on eBay, and saw a used one for $120 or Offer.
But if you need it regularly, and you have limited bench space, and you need a complete set of features, and if your time is valuable (relative to building your own tool), then isn't it a good investment...? For full disclosure, I should perhaps mention that I got my personal Beagle for free, as a prize in a Microchip design contest. :-)

That argument doesn't hold a drop of water. If I discover my curve tracer is down and I'm trying

If I'm trying to drive to Edmonton to see a play and my car breaks down, should I seek car repair
help in a group specializing in Alberta playwrites?

Point taken, although your counter-examples are a bit extreme. I should not have suggested "application" without more context.
My counter-counter-point is: When your Tek curve tracer is broken, do you need a Curve Tracer forum, or a more general Tek forum (like this one)? The former is impractical I think, just like (I suspect) a L.A. forum would be, for the reasons already discussed.
Car breaks down (you didn't mention which Tool is involved): Would you go looking for a "tool forum"? No, most likely a "Ford forum" is the practical answer. That's my point.

Hi satbeginner
Sorry I accidentally deleted those picture.
For temperature measurement I have one built using lm 35 temperature
sensor and I can attach it with crocodile clip to the heat sink.
I deleted those pictures not to be confused with so many photos.
Sorry
Thanks

Hi Saroj,

yes, of course you can, but I would keep at least one picture showing the
extra pulses, because that could help others to identify a similar problem
with the switcher chip.
You mean the pictures in your album:

I still assume you use a 10x probe, because the readout still looks like
10x lower than expected :-)

Do you have a way of measuring the temperature of the Power FET when the
scope is operational?

Starting to look good.
