Slot 1 (SC242)
Slot 1, also called SC242 (slot connector 242 pins), is used by the SEC design that is used 
with the cartridge-type Pentium II/III and Celeron processors (see Figure).

layout.
Slot 2 (SC330)
Slot   2,   otherwise   called   SC330   (slot 
connector 330 pins), is used on high-
end  motherboards  that   support  the 
Pentium II Xeon and Pentium III Xeon 
processors.  Figure.    shows the  Slot 2 
connector.

The  Pentium  II Xeon and Pentium III Xeon processors   are designed in  a cartridge 
similar to, but larger than, that used for the standard Pentium II/III. Figure. shows the 
Xeon cartridge.

Slot  2 motherboards  were used  in  higher-end 
systems such as workstations or servers based on 
the Pentium  II  Xeon  or   Pentium III   Xeon.  These 
versions   of   the   Xeon   differ   from   the   standard 
Pentium II and slot-based Pentium III mainly by 
virtue of having full-core speed L2 cache, and in 
some versions more of it. The additional pins allow for additional signals needed by 
multiple processors.
