Bob;
If anyone pin on any one chip failed to make contact, the whole bank will
not be recognized. It can be unbelievably easy to "miss-install" one of
the chips. Even with good lighting and eyesight, you really need a
magnifying glass to verify that none of the pins have "folded under".
In particular some of the chips are supplied with very soft leads and
these are the worst.
