Zuul

I contemplated the conductive paint approach...but realized I have around 35-40 different "retro" comps and consoles I need to get to town on so I bought a "usb microscope" readily available on ebay, Best £15 spent. Resolution is ok, lags about 1/5th of a second. For soldering iron I'd suggest one with temp control because I set mine at 350C and almost fried everything. Those joints are tiny so start of with 230C, use flux.
