More Info

All sockets prior to Socket 1 were undesignated, prior to that CPUs were soldered directly onto the motherboard.

Wikipedia Entry

Socket 1 was the second of a series of standard sockets created by Intel into which various x86 microprocessors were plugged. It was an upgrade to Intel's first standard 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 into the older socket.

Socket 1 was a 169 pin LIF/ZIF PGA (17x17) socket suitable for the 5v, 16-33 MHz 486 SX, 486 DX, 486 DX2 and DX4 Overdrive processors.
