My one assembled prototype is inside my system, so here's a picture of the raw PCB. It mounts to a standard keystone brand slot bracket
Do you have a photo of the interface cable that goes from this PCB to the DIP socket on the motherboard?

No, it's just a 24 pin ribbon cable with DIP24 IDC connectors on either end. Imagine a 8088 to 286 accelerator card's CPU cable
I can already envision what it looks like, however my purpose for the question was the hope that you would provide a photo of the finished product and interface cable to inspire others who might want to follow suit. I do not have this motherboard, so it wouldn't be for me, but for those who stumble upon this post who want to do something similar.

Pretty good, why ? Is it about removing the via keyboard controller and replacing it with your board ?

Yes - the procedure is to desolder the DIP-24 Via KBC and replace it with a DIP-24 socket
Then you make a length of 24c ribbon cable with the DIP-24 IDC connectors on both ends, plug one end into your fresh socket and the other into the mod board. You also need to grab IRQ 12 from somewhere on the board, there is a via nearby.
I can share the gerber files with you if you're interested in assembling your own mod board, or I could make you one and sell it- I have exactly enough components (DIP-40 KBC notwithstanding) to make one more
Ah, thanks for the offer! I can make one myself having the gerber files, but first I wanna be sure I really wanna do it (as a matter of fact that it requires extensive modification of the original mobo). I let you know if I'm interested.
I wouldn't exactly call socketing one single IC extensive modification, but it's up to you! You can always put the original KBC back in the socket if you decide to revert. I'm attaching the gerbers to this post
Thanks!
