I have been looking out for a 14MB ram card for my 180 powerbook for quite some time without success. Recently, i started thinking that maybe it would be possible to add the missing ram chips to the existing dram module already in there (4mb)??

Afaik, the board is populated with TC518512FTL-80 (Toshiba) chips and these can be bought still.

Would it be as simple as soldering on 6 more of these to gain the full 14MB or is it more complicated than that?
