MKARS 80 Build
More /P Construction
Wednesday
1:45 Setup work bench /P and started building.
Neatly bagged components and a smart board with easy to read markings aided construction. Spent some time referring to the printed board layout; sometimes no matter how hard you look you just can't see the place for the next component.
