Slot 1 is a departure from the square ZIFPGA/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. [bus rates?] (1999-08-04)
