Desoldering ram chips is more effort then its worth.
That depends on the RAM chips, how rare they are, and how much you need
them.
The old days of recovering tons of 64kx1 or 256Kx1 chips that way are
long gone, though.
Why? Because you can't find boards full of them any more, or because such
boards are actually useful complete (this certainly applies to some
Unibux memory boards, S100 boards, PERQ memory boards, etc). Or because
you can't find a use for 4164s or 41256s? (I certainly can!)

From what I have seen boards of the vintage that would
have the chips I am
looking for (256kx4) are either in somebody's parts bin
(which is why I
asked here) already or have been scrapped a while ago. Most of these chips
haven't been used since the early 90's making them at least 10 years old.
Some other oddball chips I am looking for are 256kx8 VRAM 70ns SOJ for my
old matrox vlb card (most boards use higher density vram chips).
