Reference: Pentium III processor codes

[Karlsweldt]

The following chart is for reference to the Intel ® Pentium III class processor family. The stepping code is the true identity of the processor capabilities. Most popular was the 'Socket 370" design, but also the "SECC" or Single-Edge Cartridge Connector was widely used.
AMD had a similar cartridge design, but it was known as "Slot A". The two entities are not compatible!

Pentium III-Models
Katmai (250 nm) May 1999
Coppermine (180 nm) Mar 2000
Coppermine T (180 nm) Aug 2000
Tualatin (130 nm) Apr 2001

From: http://www.cpu-world.com/sspec/Pentium%20III.html
** FC-PGA is for 'flip-chip' pin grid array (Socket 370)
** SECC is for single-edge cartridge connector
** uFC-BGA or "socket M" was an early 478-pin predecessor to the Pentium 4

Is the SECC also known as Slot 1?

[Karlsweldt]

SECC refers to "single edge contact cartridge " which is how the 'slot 1' by Intel and the 'slot A' by AMD are designed.
They are not interchangeable, having different contact sizes and circuitry.
