Universal Test Sockets
Standard DIP packages come in two widths (measured between pin centers), 0.3 in (7.62 mm) (skinny dip) for smaller devices (8-28 pin) and 0.6 in (15.24 mm) for larger devices (24-40 pin). To allow design of programmers and similar devices that supported a range of devices some in skinny dip and some in full width dip universal test sockets are produced. These have wide slots into which the pins drop allowing both 0.3 in and 0.6 in devices to be inserted.

Famous quotes containing the words universal, test and/or sockets:
“Without doubt God is the universal moving force, but each being is moved according to the nature that God has given it.... He directs angels, man, animals, brute matter, in sum all created things, but each according to its nature, and man having been created free, he is freely led. This rule is truly the eternal law and in it we must believe.”
—Joseph De Maistre (17531821)
“We do not quite say that the new is more valuable because it fits in; but its fitting in is a test of its valuea test, it is true, which can only be slowly and cautiously applied, for we are none of us infallible judges of conformity.”
—T.S. (Thomas Stearns)
“And in their blazing solitude
The stars sang in their sockets through the night:
Blow bright, blow bright
The coal of this unquickened world.”
—Philip Larkin (19221986)
