This sample is not an engineering sample, but it's a rarity. It's a Pentium II built on a Socket 370. This CPU was used for evaluation purpose and to validate Desktop motherboard with Mobile CPU. The CPU used is a Mobile Pentium II Processor with 256 KB built-in L2 cache and built on the Dixon Core. This sample is clocked at 266 MHz (4.0 * 66 MHz) and works fine with lots of Socket 370 Motherboard. It requires a voltage as low as 1.5 Volt, but works without any problem at 2.0 Volts with a big cooler.
