my board has a header - but I am not sure, if the preowner maybe had soldered it in.
I measured the middle pin which seems to be ground and the 4th pin is cutted -
Board ist orientated like this: Isa, PCI, PS2 header, AT Keyboard
Referring to this numbering:
1
2
3: gnd
4: cutted ( NC?)
5
I measured the remaining 3 Pins assuming that pin 4 is NC - all got 5V - so I tried this 6 Versions:
Version 1:

Version 2:

Nothing works ...
What I was thinking about is, that maybe the keyboard controller is not capable of ps2/mouse - mine reads on the backside
RAMIF
B31810 TS2
9510B TAIWAN
and on the frontside
AMIKEY tm-2
(c) '85-'92 Am. Megatrends Inc.
But since I do not have another Controller - so currently the ps2 port project is on hold
