Todd just a quick note to let you know the V06c version of the mezzanine boards checked out fine on the 16MG S100 RAM board. I hammered them fairly good with the 80386 board, they did fine.
Soldering the chips on to the board is quite tricky. I found it best to aligen one corner, then orientate the chip and do the diagonally opposite corner, then run the salder tip along the pins. With a wet tip there is enough solder on the pins and the board for contact. However I had one chip where the pin did not make contact, took me a while to locate it. These boards are definatly not for anybody with shakey hands
