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:
“I have simplified my politics into an utter detestation of all existing governments; and, as it is the shortest and most agreeable and summary feeling imaginable, the first moment of an universal republic would convert me into an advocate for single and uncontradicted despotism. The fact is, riches are power, and poverty is slavery all over the earth, and one sort of establishment is no better, nor worse, for a people than another.”
—George Gordon Noel Byron (1788–1824)
“There is held to be no surer test of civilisation than the increase per head of the consumption of alcohol and tobacco. Yet alcohol and tobacco are recognisable poisons, so that their consumption has only to be carried far enough to destroy civilisation altogether.”
—Havelock Ellis (1859–1939)
“Webster was much possessed by death
And saw the skull beneath the skin;
And breastless creatures under ground
Leaned backward with a lipless grin.
Daffodil bulbs instead of balls
Stared from the sockets of the eyes!”
—T.S. (Thomas Stearns)
