This article is part of the CPU socket series

Slot 1 refers to the physical and electrical specification for the connector used by some of Intel's microprocessors, including the Pentium Pro, Celeron, Pentium II and the Pentium III. Both single and dual processor configurations were implemented.

Intel reverted to the traditional socket interface with the release of Socket 370 in 1999.
