I once did repairs of consumer electronics and replaced a few chips with 
64 pins.  I made a tiny tip for my soldering iron out of wire (I think it 
was #22) and worked out a way of threading a fine wire up under the pins 
of the IC where they enter the body of the chip.  After removing as much 
solder as I could with solder wick, I'd pull each leg up off the board 
with the wire, starting at one end.  It took patience but it worked fine.

There's no way I'd have bothered with a 1500 pin device.  Actually, 
portable CD players, radios, etc. are so cheap now it isn't worth 
replacing the 64 pin devices any more.
