Sean,

It works again -- congratulations !!!!!

This is great news, indeed. Another good news is that now, you have a good knowledge of how this instrument works !
You may want to have a close look at surrounding soldered joints, especially the R's and C's in the Wien bridge and relay K1, because one of them was the culprit when the oscillator was running at 12 kHz. A defective or mis-soldered Q1 couldn't change the frequency.
The next step is calibration... of course very few of us are lucky enough to have all the required standard capacitors and inductors. But if you're willing to spend some time on the project, there's a number of things you can do to calibrate capacitors and inductors from your spare parts bin. If you'd like to share some ideas on this, just let me (let us) know.
And if you want to replace Q1, I have a few New Old Stock 1855-0082s (not a "close equivalent", they're the real thing from HP!) on hand. Just let me know.

Again, congratulations for a job well done. You just saved another HP instrument from the scrap heap !!!!

Not?sure to what?avail, but I decided to chime in regarding two of the aforementioned topics.?

First, I came to understand that corruption works on a different scale in Europe and in the US.?

I'd say that in Europe - particularly in the eastern half thereof -, corruption is widespread on?average, but it's proportional to longitude and inversely proportional to latitude (sorry, Spain, Italy, Greece, Balkans and Central and Eastern Europe).:)

Where I live (admittedly kind of a private dung heap of a petty tyrant nowadays), corruption has always been pervasive from the highest to the lowest levels of government. Although the criminal justice system has?been generally functional, in the 90s and early 2000s you were definitely able to get out of a traffic ticket pretty easily by paying a 50 or 100 EUR bribe.

In most of Western Europe, buying your?way out of traffic violations or crimes is basically unheard of, although obviously corruption is there in the higher tiers of government. You know, where the money is. The EU exercises pretty lax control over the funds it pours into R&D and infrastructure projects and this naturally paves the way for all kinds of abuse.

I came to understand that the situation in the US is similar to that in Western Europe, with an important catch: the mega-corporations over there have taken corruption to an entirely different level. If you follow the course of events regarding the recently proposed Right to Repair legislation in several states, it becomes clear that lobbyists - on the payroll of interest groups of major players in industry and commerce - have derailed bills that would've clearly benefited an enormous group of people. This is of course not the first time they've decided to get rid of rules and laws that would negatively affect their profit margins, or, conversely, introduce legislation that benefits them. And the situation has deteriorated ever since (now many decades ago) Eisenhower warned the electorate about the impending dangers of the runaway military-industrial complex. The amount of funds the federal government is handling is simply too high. This kind of influence is obviously present in Europe as well (huge corporations having their way), albeit not nearly on this scale.

Second, Tam, I'd really appreciate a link where I can see for myself that I could go to prison for libel or slander or defamation for 10 years in Germany or Austria. I've?been toying?with the idea of moving there for some time.

Cheers,

Gabor

Nah, no hard feelings man. But it is unbelievable for Americans that, in
Austria and Germany, you can go to jail 10 years simply for saying things.


An average rapist or murderer does less, by the way.

Dave,

Sorry to hear about the tornado. I’ve been through a few out here on the high plains but damage was limited to roofs, windows, and cars. No direct hits thankfully. Closest was a front porch ripped off and a tree through a kitchen window. You never forget the sound of a tornado.

On a brighter note, I have working HP 9000 Series 200 and 300 systems and HPBASIC on a Win7 Pro machine, as well as 8510B and C systems, an old PC for Teledisk and the HP LIF utilities, and a bit of software for the 8510s. I’m happy to help with any software conservation. And I have some nice single malt if you ever venture out this way!

Either way, I wish you good success in cleaning up.

The wind kind. Thanks. We are ok, but there was some building damage
and a couple of days without power. Some friends are coming out to help
pull some troublesome latticework off of the front of the museum
building; it partially broke loose during the storm on Tuesday night.

Bleach didn't work; I had to throw that underwear away. It was days
ago and we are still a bit rattled here.

As for the topic
nazis: usually, I have seen these at the Scopes r Us mailing list. Here,
not so much. But you, being owner, probably get more flak than I do.

I'm just a moderator, not the owner, but yes, every so often one of
these people who lack either a hobby or a delete key pops up.
Admittedly the problem is much less severe here than on other mailing lists.

As for RMB: I would use Visual Basic and a NI GPIB card. Works out of
the box. Here is an example, which should be easy to follow albeit it is
in Csharp:

No Windows. Seriously man, life is too short for that garbage. But
thanks for the effort.

But either way, we're discussing getting the existing software
running, not general means to access instruments via HPIB. The eventual
goal would be to port the existing software out of RMB and to something
generalized and maintainable (and, forgive me, but moving from one
proprietary language to another is probably not the best idea) and more
accessible. But we must first access, and probably run, the original
software. A lot of it is not available in source form, so we'll
probably end up sniffing HPIB traffic to figure out what it does.

Possible to scan?

typing this on a Linux box: for instrument control, go Windows or go bust.

BS. I've done instrument control for 2.5 decades, with great success
and wanting for nothing, and I have never run Windows.

Adding an extra layer of madness which is LinuxGPIB on top of already
flaky GPIB implementations in most test kit is not something you want to
do.

If that's the way you want to do it, be my guest, but I've never used
LinuxGPIB either.

As for the software: I gave, somewhere, a printed cal manual for the
4195A as mine was sold to a research institute in the UDSSR originally.
I would be surprised if it does not hold the source code for the apps. I
can go and dig, if you so desire.

That would be very handy if the source is included. The idea would be
to create a functional clone, of course, but reading the sources would
make short work of that.
