A friend of mine would like to expand the memory on his Compaq
portable using 256K chips.  He has been told that he needs a new
decoder PROM and possibly some special tool.

Questions:  1) Is there anything more to the job than simple 
chip extraction and insertion?  2) Is the speed of the chips critical?
I assume 150 is fine.  3) Where is a good place to get the memory
chips AND the decoder PROM(s?) AND (if necessary) any special tools?
4) Any tips on how to make the job easier and/or less prone to error?

Any and all help greatly appreciated.
