Title: Need advice on making a hand-wired NKRO programmable matrix?
Post by: wes1099 on Mon, 13 October 2014, 12:29:56

I was thinking about buying an Apple M0110, but I wanted to know how hard it would be to hand-wire an NKRO matrix with a teensy. I have seen post about doing exactly this but I can't seem to find anything with clear information explaining exactly how to do it.

Here's a post about it:

Basically you wire up all the rows with diodes and columns with jumpers. Make sure the diodes are oriented correctly. Then you plug it all into a teensy and install some firmware on it.

Let me know if you run into more specific issues and I can help you out, but that's some good general info right there.

Thanks! Hopefully I can snipe the board off of ebay, if not, oh well...
