Siemens Unity 2 Super Silent Keyboard

[Prelim]

got this beautiful board recently, unused and just with some micro-scratches from storage. Probably made by GMK, with pristine caps




(seeker wheels are made of steel/alu)



(hellgrau doubleshots with side printed legends)


(PS/2 and USB connections)





(2xAA batteries on the back, anyone knows for what it is?)


(naked)


(diodes in all the switches, NKRO model)


(rubber membrane in function keys, makes the switches more silent but mushy)


hope you enjoy as much as I do

[Prelim]

humm, that's strange...

In mine the membrane is only on the audio funtions keys, which makes sense! How about the batteries, do you know for what is for?

[Muirium]

Does it work?

I'm thinking the batteries could be something to do with those seeker wheels. This thing could have been made for specific software, that does things beyond the standard protocol. I wouldn't be surprised if the wheels don't turn up on a regular host. Indeed, I wouldn't even be shocked if it *needed* both USB and PS/2 plugged in together to fully function! Though that would be quite kooky…

[Prelim]

can it be reprogramed to act like a scroll instead?

[Muirium]

Aha!

Disappointing, indeed. Everyone loves knobs! But knobs are inherently analog things, needing more finesse than spitting out repeating letters.
