Slot 1 refers to the physical and electrical specification for the connector used by some of Intel's microprocessors, including the Celeron, Pentium II and the Pentium III. Both single and dual processor configurations were implemented.
Slot 1 was a departure from the square ZIF PGA/SPGA sockets used for the Pentium and earlier processors. Instead, the processor is mounted on a Single Edge Connector Cartridge (SECC), much like a PCI slot, but with a 242-lead edge-connector.
The Slot 1 specification allows for higher bus rates than Socket 7. Slot 1 motherboards use the GTL+ bus protocol.
Some Pentium-II 450MHz processors, and all slot-1 Pentium-III's, came in the improved SECC2 variety.
