ok, the M-board is screwed down. It had some solder stars around the holes on the bottom, perhaps to gnd it to the case thru the metal bumps on the case sheet metal panel, but I didn't see any traces from those on the board.

I was able to match up enuff holes to use 4 metal machine screws - I guess that will be adequate, and that no washers are needed to spread the force.

For others doing this: find a Phillips screwdriver that can hold the screws attached until they are threaded (I used lip balm). Forceps will be needed to remove the little metal screws you drop onto the circuit boards. Also, a small right angle mirror on a stick can help you figure out which side of a connector has the metal connections on it.

A lot of small pins you see sticking out of various components are not for connectors - they are for jumpers to set things up in hardware a particular way.

Forceps = tweezers
