Information on G80-5000 replacement PCBs.

[photekq]

I've spotted these replacement 5000 PCBs a few times before. The only actual information I could find on them was from Sixty. He said :

Sometime in 2006 some Korean guys re-created the PCB for the rare Cherry G80-5000, because US Layout versions were nearly impossible to find.

I'm wondering if anyone knows if the files for these were made available? I would love to be able to get some.
