First of all - it has been a VERY long time since I last wrote something here. I think it must be at least one year...

During this time some water has been flowing under the bridge.

I finally succeeded in destroying my Old and Rusty Digital Alpha-server. That machine dated from 1989 so maybe it was only a decent thing to knock it down.

As i work for the quite big and very blue company I of course now have a series X (System x3500 M2) server humming under my table. That thing has capacity and speed for the next 10 years (I hope).

Now, since I still fiddle with electronics and because I have an almost endless supply of outdated and some not-so-outdated components I usually need good access to component data sheets. The biggest datasheet archivers in the net have quite large collection of this material but IMHO their search engines suck. In addition to that - they seem to have tendency to include all sorts of advertising material on their pages - and some also embed that stuff into the documents. Yuk....

So as I am a programmer and as I also have at least minimum understanding on databases and how to organize a document archiving system I just created one for myself.

I know there are some companies who do not like their documents being "archived" this way so I am prepared to flag certain files as "Private" after which these no longer can be seen outside my local LAN.

There are some features in this thing that I have not seen anywhere in the NET.
- The search drills down into zipped files
- Zipped HTML pages can be browsed - for example the AVR source code documentation (Doxygen).
- Documents can be downloaded in multiple formats

At the moment the archive has more than 50000 documents and if the unzipped versions are counted the figure goes beyond 100000. Not a lot - but quite many are closely related to AVR (well, perhaps the Vacuum tube datasheets as not that close)....

That all being said:

Check the thing

Awesome. Thanks for the August 15th 1955 data sheet detailing my Raytheon CK1049 G-M counter tubes, a pending project.

First of all the thanks should go to Frank Philipse who has been collecting a HUGE datasheet archive which is dedicated to vacuum tubes and their accessories only. Frank's pages are also completely free of ads which is really rare these days.
Frank's Electron tube Pages

I need this sort of data since I still build and repair radios having that warm glow inside.

Generating the anode voltage at kilovolt class (750V+) required by that Geiger-Müller tube will be an interesting project by itself. Another interesting part will be the MCU interface since this tube must have output impedance in the megaohm class. Combinig high voltage and high impedance input is not going to be trivial with semiconductors.

Maybe a JFET buffer with clamping diodes in the input. The diodes should have low off capacitance to avoid signal rounding and to be able to separate the pulses.

Then again - one can always use a vacuum tube for buffering. For example a nuvistor 6DS4 would do just fine and would not require any safety measures on the grid.

Ouch - now there is real evicendce that this forum is highly addictive - being absent only 5 months feels like years ...

Hey Cliff.. Jul 14, 2010 if my eyes are not failing me..

Hi Esko, nice to hear from you!

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.
