Socket 1, originally called the "OverDrive" socket, was the second of a series of standardCPU sockets created byIntel into which variousx86microprocessors were inserted. It was an upgrade to Intel's first standard 169-pinpin grid array (PGA) socket and the first with an official designation. Socket 1 was intended as a 486 upgrade socket, and added one extra pin to prevent upgrade chips from being inserted incorrectly.
Socket 1 was a 169-pinzero insertion force (ZIF) 17×17pin grid array (PGA) socket suitable for the 5-volt, 16 to 33MHz486 SX,486 DX,486 DX2 and486 OverDrive processors.[1]
