Ok let me clarify: diodes can be the through-hole type, similar to phantom, or you can use SMD diodes, same size as all other korean keyboards. The PCB is labeled so you should know where all the other SMD components go.
I can edit and upload a video on this one in a few weeks. Programming should be the same way as GH60 or phantom since it also uses the Atmega controller. I'm not sure if there are any dedicated software for it.
