Subject:  Changing RAM ICs

Recently there has been some discussion on changing the RAM chips on
the Mac.  At the risk of redundancy, I have two questions:

1) Has it actually been determined that you can replace the existing
RAMs with new ones (256K I guess) to increase the memory size?  The
last I had heard on here, there was some question as to whether that
was all that needed to be done.

2) It puzzles me that no one has suggested using a desoldering pump to
remove the RAMs... I have often used a desoldering pump to extract
ICs on our large multilayer circuit boards in our ``mainframe'' machines
here, with no problems and no damage either to the circuit board or the
chips.  The desoldering pumps cost around $12, compared to the cost
of cutting out the RAMs...
