  But if that is the case, I'd just grab a
solder
 sucker and desolder banks 
 0 and 1 and fit turned-pin sockets in place of them.

  It occurred to whilst perched atop a big fat rock
 that placing a circuit board in shallow tray of cool
 water, component side down would probably eliminate
 the possibility of smoking a chip while desoldering,
 with a wick or whatever. Sound reasonable? 
It shouldn't be necessary. Provided you use a temperature-controlled 
soldering iron (and don't have it too cold -- you want it to melt the 
solder before the chip and PCB have a chance to get too hot), you will 
not damage the IC.

In any case, you should be more worried about damaging the PCB (for 
example the through-hole plating) than the chips. 64K DRAMs are not hard 
to get, after all. In fact, if I wasn't sure of my abilities to desolder 
the ICs, I'd cut the pins off them and then desolder them one at time 
...
 from the PCB.
