Any idea what went wrong with this board when I mirrored the voltage DIPs. So instead of 2.4V I set it up to 3.4V and something was broken at power on. Smelled a little funny. I thought I fried the CPU. But after trying other CPUs with proper settings it seems the board went bad. It a nice little board I'd like to get it fixed.

Any idea where to start troubleshooting? For starters I only have a multimeter 😉

Thanks
