I have a tb11 from Nissmo (televerket production) which I'd like to start using. It has a db25 connector and I really don't know where to start other than here. My computer has windows 10 and is modern in the sense that it doesn't have any "legacy connectors". Any help from here?
Thank you for your time.

Posting photos would help. Your best chances are reverse engineering the protocol with a protocol converter, or a replacement controller. This is true for just about any non PS/2 or USB keyboard. Good luck.

The keyboard and plug, for starters

A natal astrological chart wouldn't hurt either, if you really aim for good sync with this thing.

All I'll say is that, given the manufacturing date of my XXK, it was, like,
its destiny to be filled with X keycaps. Turns out that wasn't really my idea, but instead it was the Universe fulfilling its need through me.

This one?
With it being a
male DB-25 plug, I would rule out it being RS-232 serial interface.
Perhaps a standard parallel port (which used that gender of DB-25), but more likely it is exposing the whole matrix on the pins -- intended to be scanned from the host computer.
You'd have to open it up and take a look at where the wires go and what kind of electronic components there are inside (if any, except for switches).

Yeah, that's the one. I'll try and open it tonight if that helps.
