I'm building a Fairlight CMI - Episode 18 New Cards & Parts & DRILLING !

A big episode ! New parts arrive, existing cards DRILLED and modified, back plates have to be make, cut, painted and lasered.
Things that should work, ,don't, and things that shouldn't work, DO !
Overall many simple things are somehow baffling to me... and even watching this video now I realize what an idiot I am. :)
