Socket 370
     
         (PGA370) A physical and
        electrical specification for a {motherboard} {processor}
        socket.  Socket 370 uses a square {SPGA} {ZIF} socket with 370
        pins, arranged 37x37 (sometimes described as 19x19).
     
        {Intel} originally designed Socket 370 for {PPGA} Celeron
        processors.  Newer Socket 370 motherboards additionally
        support {FC-PGA} Celeron and {Pentium III} processors.
     
        The difference between the two versions is electrical;
        some pins are used differently and voltage requirements have
        been changed from Intel's {VRM 8.2} to {VRM 8.4}.  In
        addition, Celeron processors require a 66 MHz front side bus
        ({FSB}), and Pentium III processors require a 100/133 MHz FSB.
     
        Some older Socket 370 motherboards support VRM 8.4 and
        variable bus speeds, so adapters are available that convert
        the socket pinout to allow FC-PGA processors to work.
     
        {VIA}'s {Cyrix III} processor was designed to work with
        Socket 370 motherboards.
