Compatibility Cherry G80-3000 pcb`s

having a hard time to find reliable informations, so i ask here!
Does anybody know if the pcb size and the key arrangement of the old din version from the early 90`s are compatible with newer ps/2 or USB versions.

Someone offered me a custom G80-3000HAD with a solid pearwood case and the horrible MY Switches. Later versions of the keyboard were sold with mx black or blue. So i wondered if i could replace the pcb with a newer one with mx switches.
