Slot 1
A 242-pin slot on the motherboard that holds Intel CPU modules including the Intel Single Edge Contact Cartridge (SECC and SECC2) and Single Edge Processor Package (SEPP). The Pentium II was the first to use Slot 1. Slot 1 is a narrow slot like a PCI bus slot, not a small rectangular chip socket. See Slot 2, SECC and Slot A.

| (hardware, standard) | Slot 1 - The physical and electrical specification
for the connector used by some of Intel's microprocessor
cards, currently (August 1999) the SEPP Celeron and the
SECC Pentium II. Slot 1 is a departure from the square ZIF PGA/SPGA sockets used by Pentium and earlier processors, the processor being mounted on a card, 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. See also Slot 2, Slot A. |
