IBM 6341739 NKRO issues

[harjoat]

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.

Something is going wrong converter-side. These have NKRO, I confirmed this myself. That said, my OmniKey has similar issues when using the converter I think.

I'll reconnect the converter and hopefully it works. If not I'll probably just take it off and throw it on my Japanese version and see if my luck changes.

I just recompiled my TMK firmware to see if I could enable NKRO for my 6112884 and it works just fine

(using this online tester.... before firmware change i had 6KRO... after.... NKRO https://www.microsoft.com/appliedsciences/antighostingexplained.mspx )

I am using a hasu rev2 converter, ...I don't have my teensy with me right now, so I can't test that.. but my guess is that isn't the problem, if its working at all the only thing that I can imagine might be the issue hardware wise is if you don't have a pull up resistor on it (an electrical concept I don't fully understand yet, but implemented because hasu said to).

if you have that implemented, maybe give TMK a try... I could give you some info on making it work with the teensy if need be

oh I think I read it wrong..

if this is using the conversion that replaces the onboard chip with a teensy...... got no idea on that one!
