I just added another keyboard to the wiki (https://deskthority.net/wiki/Siemens_AK/U6). That's a nice find, thank you for adding it. I've moved it to /wiki/Siemens_97801-132 , as AK/U6 is not the model name but the production stamp. We've already got a successor of it in the wiki, which is rubberdo...

Something made by Sasse, maybe? Like this one?

There are so many things to love about this board, but the switches are definitely not among its strengths. They are way too scratchy, but I was surprised how low-profile they are, in particular by the "standards" of the early '80s. The toggle switches on top look and feel nice though. Here is a po...

Anyone have an idea? Siemens or Robotran would be my guess..

Spoiler:

Definitely Robotron — Siemens put such top-hat caps only on low-profile switches.

Supposed to be an old Siemens keyboard. Any guess on use-case and switches? Did you get any more info on this keyboard? I found a similar looking one, but with some extra keys top right. Siemens.jpg Unfortunately not :? That's a Siemens T1000 teletypewriter keyboard. We had a similar one rather ear...

Linear switches in a keyboard that was found lying outside a textile factory. The keyboard appears to have been part of a computerised weaving machine, and I can't find anything about the switches that it uses. Has anyone seen them before? They've got a pretty short travel, are fairly smooth, and t...

I would do the following with a device that has not been switched on for decades: https://antiqueradio.org/dimbulb.htm

Also, what do you think of this one ? https://i.ebayimg.com/images/g/icUAAOSwBoxeB1t4/s-l1600.jpg A geekhack thread mentions Cherry ML, but these caps are also present on Rubber domes and Siemens STB switches. So I don't really know I'd assume that one to have STB switches – the lasered tops speak ...

Two old siemens boards with STB 21 switches and AT compatibility for any Swedish buyers. Thank you for sharing this. The field programmer board on the lower image is quite interesting - you rarely find them offered with case and cable. Beware of the other one, though. It's not easy with this style ...

A Siemens keyboard of unknown model. Uses Siemens's STB switches. That's a Siemens TA-BS/1200 teletypewriter keyboard. There seem to be quite a number of variants of it. This one is not in the overview photo not because it's not worthy; it's simply TOO BIG. A stage light controller apparently, with...

I new, I've seen it somewhere, but now I remember, kbdbabel has the pinout:

Note that the scan codes are likely to need remapping.

This keyboard was made by Falco for their F500 terminal, which was sold by Siemens as an operator's terminal for their HICOM 300-series telephone exchanges around 1990. Here you can find photos of it Falco branding: http://bitsavers.trailing-edge.com/pdf/falco/Falco_F500/pictures/ Siemens branding: ...

Function keys on the monitor, underneath dynamic labels. Neat!

Prices were steeply falling also for original parts. Prices from the 1990ies already cannot really be compared with those from the mid 1980ies. In 1996, you paid for a new 102-key IBM-labelled model M just about half the price of 1986; adjusted for inflation it actually was just about a third of the...

I showed some parts catalogs of IBM terminals in my Model F review - prices for several Models F were shown in that price list, and they numbered in the $300-400+ range. That list was from 1984 iirc. The average IBM-keyboard shop prices I posted in the other thread correspond to about $ 300 in 1986...

After seeing it in person, I am confident somebody took an old Datasaab keyboard, desoldered the switches, put them in a strange layout and hand wired them. Still would like to know which machine this originally came from though. datasaab.jpg This keyboard came from an Alfaskop 3500 series terminal...

I always liked the tandberg header with the previous board version. Maybe this one is a bit 'square' - it's my fist attempt. edit: This way, it seems to look better:

https://deskthority.net/download/file.php?id=50879 Does anyone know what this is? The keycaps are vaguely similar to Siemens and RAFI but have a more rectangular shape. This used to be a German army keyboard for a PC that does encrypted communication. Switches should be Sasse, cf. https://www.flick...

unknown board but I'd bet Siemens STB series of switches

SIemens KBPC SX.
Sorry, no STBs — boards with that keycap style have rubber domes.

No need to rewire. You only need to make a ps2 to usb converter and modify its software to swallow the 0x80 prefix and remap the code following it. For instance, you could use Hasu's code, https://github.com/tmk/tmk_keyboard, and change the matrix_scan function in converter/ps2_usb/matrix.c accordin...

What it means exactly is that if one of the extra keys is pressed, the keyboard first sends scan code 0x80 and then the specific code for the key. For instance, the make code for "COMPOSE CHR" is the sequence 0x80, 0x1D. The 0x80 prefix gets ignored; hence, Switch Hitter sees only 0x1D and thinks it...

The 8048 wasn't programmable; hence, it doesn't show up in compatibility lists. The ROM bits were hardwired - created by photolithography along with the other transistors on the chip. However, the 8048 can be read. This project describes how this can be done with very little hardware (+5V plus +12V ...

Here's a Tandberg Data keyboard for sale in the Paris area for just 5€. Local pickup only unfortunately. https://img7.leboncoin.fr/ad-large/32a0b6b2a426b9bb693705d7da28e1babb8e31b0.jpg Is anybody familiar with this brand ?

That's a Digital DECwriter-III from around 1980. They were used as teletypewriters but more often as printing terminals. DECwriters were the preferred operator/master consoles not only for VAXes and PDPs but also for similar systems of the era that were made by other manufactures (which, as the stic...
