SOIC	small outline IC.  Package is plastic, rectangular in shape, and
	has two rows of contacts along the long dimension.  Contacts are
	on 50mil centers (as opposed to 100mil centers of DIPs), and formed
	in a "gullwing" arrangement for surface mounting as opposed to the
	through-hole mounting of DIPs.  They are approximately a 50% shrink
	of a DIP in all dimensions.

PLCC	plastic leaded chip carrier.  If the pins on your mystery package
	are J-shaped so that they make surface contact, then that's what
	you have.

LCC	This is generally a "ceramic leadless chip carrier" an LCC.  If you've
	got an AT, your 80286 is probably in an LCC package.

LDCC	I've seen this used for a "ceramic leaded chip carrier", but I'm
	not sure if it is a common terminology.  The main difference between
	a "leaded" and a "leadless" part is the former may be surface-mounted
	directly onto a board (although socketing is also possible), and the
	latter always requires a socket.

Once you get all this memorized...I'll tell you about QUIP's :-)
