Just in case someone could find this Siemens-Nixdorf terminal keyboard interesting,
http://www.ebay.de/itm/111710589961
be warned that this is a rubber dome one, as you can tell by the horizontal lines that show underneath the keycaps.

Backspace ("BS") is missing; RUB OUT is an alias for DEL, not for BS. When DG boards have RUB OUT, they never have DEL, but there are boards that have both, BS and RUB OUT (or BS and DEL).

This is an idea from the late 1980s, when keyboards were collocated with large cathode-ray-tube monitors, which charged the users with static electricity. TTL circuitry had just been replaced by CMOS technology, which was much more sensitive against static discharges, so means were sought to dischar...

Since we like it "mechanical", rectal administration should be the way to go. :roll:

Jo, moin Seebart.

To my mind, the gallery seems complete. Disassembly instructions I'd only expect if anything was obscure.
Some information on the production years would be nice, though.

Thanks a lot for the review, though it made me a bit melancholic. I bought an FK-2002 in May 1989 (white Alps), the first tactile board I owned and I was quite proud of it. The badge and the label strip were flipped around and sported my own logo and labels. Mine had an Inverse/Normal switch that sw...

Sorry to disappoint you, but (as with the compudent board) these are mechanical keys, not hall effect ones. In photo no.5 (key caps off) you can actually see the metal leafs and the noses of the sliders, which hold them up from their counter contacts. And in photo no.7 (backside of the pcb) you can ...

Well, for the time being that layout is just fantasy ("ideal"), but those slim keycaps do exist:

Notice this very special Mu keycap. The µ on the step. That`s dental style. :mrgreen: What`s the printing here guys? I reckon, this would be diagnosed as an occlusolingual discoloration. :D These are mechanical switches (RS 76 M) - the metal leaves are clearly visible. IIRC, pink salmon sliders den...

The controller scans the matrix with a high frequency. When the controller drives the 2wasz line and one of its keys is pressed, it takes a moment till the change has been registered. If the controller moves on to the next line quicker than the signal propagates, you loose the key press. Combined wi...

Hi Daniel, here is a link to a bilingual Siemens catalog from the 1990s, http://www.datasheetarchive.com/dl/Datasheets-UEA2/DSAFRAZ0022194.pdf The section about the STB switches starts on page 80.

Tandberg used Siemens-shaped keycaps on Cherry switches, so the keycap is no good indicator.
The switches in 7bit's photos are Siemens STB 21 switches. I've updated Daniel's wiki entry and moved it to "Siemens STB".
