Special thanks to whydobearsexplod for the great backside silk and to the 40s community as a whole for enjoying my work and keeping me on my toes. The real end game are the friends we've make along the way. ## Build tips The board is meant to be used caseless. I suggest you trim all of the switch pins and make nice round solder…
