Let's see if anybody has an idea what this was for.

I have seen hundreds of ergo keyboards but I don't remember that one.

Is it something you've been involved in in Germany?

The holes around some switches must be for PCB-mounted stabiliser, and should indicate the keys's size and orientation.

It is not just an ergo keyboard…

...a flying ergo keyboard?

OK, here is the full device.

The name of the project was COSSMA (COmputer SchnellSchreibMAschine - Computer fast typewriter). It is a keyboard for chorded entry, where you type a complete syllable in one action. It was supposed to allow really fast typing way in excess of normal keyboards. And it actually did. Though it required quite some training, I never nearly mastered it.

It also had a ton of complete words and phrases. This is almost 30 years old now.

The interface it uses is ADB (Macintosh) as using PS/2 turned out to be way too messy for this application and USB was not yet around.

As a research project it ended with a patent granted on the input method and not a single unit produced for sale.

I thought about chording because you hinted you were German and I knew Siemens made a chording keyboard for Bundespost.

I thought the number of keys on this one would have ruled out chording though, as most chorded keyboards don't have nearly as many keys.

Nice. It reminded me of the NEC keyboards but doesn't have the same thumb cluster.

Only other information I can find is https://saar.infowiss.net/projekte/cossma/

This one had nothing to do with Siemens :)

The idea here was to type syllables, the position of the key blocks is somewhat related to the position of the letter in the syllable. The algorithm turning this into useful words was the part that got a patent.

Found this one in our store. We had nothing to do with this one, just got it as a reference unit for some project.

So this one is an actual shorthand keyboard. But I have no idea how to use it…
