 Since the silicon for the smaller RAMs are not being made anymore,
you can only get some of the newer, larger sizes. Other
than some old shelf stock, the original ones are getting
rare. An adapter socket solves this but hacking open an
epoxy module can be a fun thing to do. One does need to attack
with care. Cutting open a lithium battery that may still
have some un-reacted lithium can be a finger burning
experience. Have a glass of vegetable oil handy. If
you do cut into it and it lights off, dropping it into
the oil would be better than the couch. Don't drop
it in water, this can be explosive.
