Hi guys, picked up a couple of these. The one I converted using a teensy and soarers firmware is the Chinese model. I've read that it has NKRO but this doesn't seem to be true. I've been unable to use the W and TAB key at the same time (pretty annoying for online games) and unable to use the shift and WASD cluster at the same time. It seems to only have 2KRO. If anyone knows of a fix to this or what may have gone wrong please to let me know. It would be a shame to have to sell this keyboard after the effort I went through converting it.
Edit: Fixed to the correct model number ibm 6341739.
