I have a PC-to-X68k keyboard adapter for sale. It is built upon the GKA-AT adapter and fits into a small box with trailing cables with PS/2 input and X68000 output mini-DIN connectors. All in black to match the typical X68000 setup. The unit has been tested with my Expert HD.
Asking price 50 €, I won't build any more of these because it's quite a chore to fit everything into such a small enclosure, requiring double-sided mounting of components and much planning.
I'm in Sweden, but can post it world-wide.
Sent you a PM, did you receive it ?
You have PM, Parodius.
