Socket 3 was one of the series of CPU Sockets into which various x86 microprocessors were inserted. It was sometimes found alongside a secondary socket designed for a math coprocessor chip, in this case the 487. Socket 3 resulted from Intel's creation of lower voltage microprocessors. An upgrade to Socket 2, it rearranged the pin layout and omitted one pin so that 3.3 V processors could not be plugged into older 5 V only sockets.
Socket 3 was a 237-pin low insertion force (LIF) or zero insertion force (ZIF) 19×19 pin grid array (PGA) socket suitable for the 3.3 V and 5 V,
