Intel Pentium III 800EB
The Pentium III came in many variations including the 800EB. The EB model indicates that it is a 133MHz FSB version with Coppermine-core. The 800MHz model is also available with a 100MHz FSB which is usually noted without the EB-suffix.
I have another 800EB that is a few weeks older and is based on the cB0 stepping rather than cC0.
