Mist-o-kack!

Err, no, it means: crappo bullshit!

Dat Siemens!

TA, http://www.ebay.de/itm/Triumph-Adler-PC ... 2006085699

If you follow the traces, you'll find that the pads are connected like this: VCC-----[large gap]-----[small gap]-----GND This is a typical pattern for a power LED with a current-limiting resistor. Since the size and position of the small gap is a direct continuation of the pattern set by the three o...

I saw that board in the morning and it gave me an itch the whole day long. I'm glad it's been sold now.

I asked the seller to draw a cap from the Siemens he also offers, and it's a rubberdome one, as already was suggested by the lasered caps, http://www.ebay.de/itm/252388379076

Statistics say the opposite: The Bern has won where nonwhite minorities are smallest, Hillary where large fractions of the population are Blacks or Hispanics.

Often this is a bad sign: you cut the cable to indicate that the item is broken beyond repair (or not worth the repair).

Siemens RAFI(?): http://www.ebay.com/itm/181823626995 Another one: http://www.ebay.com/itm/181856146349 These have already been up for quite a while and have been listed here before. Funny that the one with German caps has English labels on the case and vice versa. Both have Siemens STB 21 switches...

Eye protection should be worn, too. At least if you do such things as clumsily as me, splashes will occur while you're brushing.

Ah, thank you very much. Now I understand: it's not "yah yah yah yah" but "kha kha kha kha!"
Hehe!

All Siemens boards with that peculiar pentagonal keycap shape have rubberdomes.

Ah, that board was made for a Siemens 3974 R "Remote Datensichtstation" (like this), the only model in the 3970 family that had RAFI keys; it quickly was superseded by the 3975 with Siemens STB keys. The board is over 30 years old and you got it NIB. Amazing.

Sorry to read about the broken plunger. I've searched through my bits and pieces and found a solitary switch that I could offer. Those are beautiful, well-preserved caps that go surprisingly well with the board, despite being from another era. They seem to be taken from a German Siemens board of the...

Curiously, there appears to be a halo of sort around the legend which can be enhanced by tweaking the light levels. This could just be an artifact of the crappy usb microscope I used to take the photo. Yep, this could very well be some local contrast enhancement artefact. See also unsharp masking .

I'll try to get them for the wiki and to see whether Siemens or RAFI caps fit (Cherry caps surely don't). Half an hour before: Dibs! [cat with big eyes] So... People aren't listening to the Cat Pics? I don't think they have ever worked... Nor has saying you want it first... ... But, whoever wins it...

interesting cherry switches: http://www.ebay.de/itm/40-Stuck-Cherry-Taster-fur-Tastaturen-Raster-19-mm-/172176687440?hash=item281687c150:g:IRkAAOSwKfVXGmJK Those are Sasse switches ; Beardsmore calls them the "B1" variant. I'll try to get them for the wiki and to see whether Siemens or RAFI caps fi...

PM'd!

Welcome to Deskthority! A Siemens PC-D keyboard from about 1984, excellent find! I used to know this board only from photos that did not show the plungers. The black plungers are a bit snappier than the red ones. In case you give up on that project, let me know ;) Oh, and I'd be interested in the "r...

I have a love-hate relationship with DEC equipment since the early 90s, when I had no PC on my office desktop but a vt330 terminal, as the DECstation I actually worked with (which had an LK250 keyboard!) was so noisy that we had to keep it in the cellar. A DECserver connected me to it and to the Vax...

Oh, what's happened here? I was just about to write that this keyboard should be compatible to a DEC LK250/450 such that a regular AT->PS/2->USB adapter chain should suffice for the beginning and the remapping can be done by means of the operating system. Or what was the initial question? edit: "Oh!...

You mean this? http://product-images.highwire.com/2546268/7c2cd6cf-3242-4919-b0cb-0d1767609db0.jpg That's a Wyse WY30 keyboard. Dynix is the catalogue software they used to use. The switches should be Cherry MX blacks. Here you can get one, http://www.movesurplus.com/product/dynix-automated-library-...

Maybe "laptop" is not the proper term for a 16 kg device. :) I've searched through my collection of Siemens documents but couldn't find a detailled hardware manual for the PG 750; however, I wouldn't expect the built-in colour monitor to support composite video - the built-in video card is VGA, so y...

Seems to be from a Siemens PG750 field programmer.

Yep, these are Sasse switches. We don't know the proper trivial name of it. The wiki page name has been changed a few days ago by Daniel Beardsmore since he thinks that the previous name, Sasse 200MN, sounds like a part number. I agree that "SPST" seems pointless (although the Siemens STB11 switch w...

Thanks for your reply - except for the travel, it exactly matches my impression.

These are STB 11 keys. I don't know the exact date when they disappeared, but the switches with red plungers were made at least until the mid 1980s. I don't know for sure what the red colour is supposed to indicate - early catalogues do not list colours and late catalogues do, but red is not on the ...

More generally, this article doesn’t really discuss it, but the proper keyboard tilt depends on the relative height of desk and chair (and the height of the typist), and the DIN standard mandates the wrong angle for the height, given their desk recommendation (angle must be “less than 15°”, but in ...

To say that Im incredibly happy to get this far is an understatement :D Well done, you! I must admit that I had a slight hope you could give up and I could get the board. :mrgreen: Thank you very much for sharing your joy! Now, it might be a good idea to leave an arduino or teensy between the keybo...

Good to see that the controller is alive and scanning. So it's still possible that it is also fine otherwise and it is the socket, the cable or the PC side which is at fault. Resistors pull the clock and data lines up to 5V so you can signal the lines simply by shorting them to ground - first the cl...
