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 "rest", too.
edit: The board was made in July 1985, the switches is March.

Are there any parts available from this keyboard? I am searching exact this keyboard to bring my Siemens PC-D back into operarion where the keyboard was lost during relocation.

Hi Gichtl, I'm sorry, IvanStroganov said he'd send me the caps but I haven't heard from him since. It's not quite easy to find replacements for these boards since Siemens used a V.11 balanced serial interface with a proprietary protocol. It's similar to that used by Tandberg, but the boards are not interchangeable. I can provide you with documentation on the protocol and suggestions for the serial driver chips in case you feel inclined to hook up another board by means of a microcontroller. In case you should get that board, I can help you with the two missing caps.

just found this topic again. I kind of forgot about it back back in the day. I still have the keyboard somewhere if there is still a need for it

It’s much too pretty to toss out… all over again.
