Maybe you need a PS2 Keybaord that can "still talk AT" (or a AT keyboard with a AT>PS2 adapter).

I have remembered it wrong and was thinking about AT and XT...

I just tested every single one of my PS2 keyboards on a 286 AT with a adapter... and all worked fine.

Alrighty. Ordered 2 mini din sockets from Reichelt for waaaaay to much money because of 6 bucks for shipping for 2 x 1 euro items. But Conrad would have been even more expensive 🥴

In the meantime I desoldered both PS/2 sockets and replaced the broken one with the one for the mouse. That way I can use the PC in the meantime and I want to use my serial mouse anyway. So it does not hurt to go without a ps/2 mouse port for a couple of days. Man what a day. But I am so glad this is solved. Thanks everybody for the lovely chat and of course the hints. 🙂

So desperate times call for desperate measures. I took a DIN-port and whipped up this contraption to test with thicker wires.
Guess what ... it works. omg!
