Have you considered blowing the melted solder away instead of sucking it
up?

Actually, I'm considering building a D16 and/or a Magic-1 computer.  See
http://www.timefracture.org and http://www.homebrewcpu.org.  Ideally I'd
like to use VME backplanes.  A 12-slot backplane with both J1 and J2
connectors is what I'd prefer, but I can't seem to find them on Ebay.
