Micro session in the garage tonight, but my first score! Got clutch!
I installed a new hose from the reservoir to the MC, filled the reservoir and let it gravity bleed for a while. Later I pushed the pedal a few times and the slave started squirting. Closed the bleed nipple and voila! Clutch operating! I still need to bleed it properly.
I also found a way to clean the brake fluid reservoir. I filled it with thinner and put a few nuts and washers into the isolated cavities. Started shaking and the brown deposits slowly cleared.
That's it for tonight.
