I find the the Desolder Stations don't work well on this kind of procedure..

I use a Controlled Temperature Iron, at 635F, and a Solder Sucker with a 
Teflon Tip, because it doesn't pull the Heat away from the Molten Solder..


Also adding Flux and Solder to already soldered items, gives more BULK 
to Suck Away..

I plan on doing this shortly to my CoCo 2s and CoCo 3..

( Once Camillus gets those 6809 and 6309 shipped out )
