NOT FOR RESALE Q335 - 80522PX233512 SL264 - 97360054-256 MALAY

This sample is particularly strange. At first sight , it seems to be a standard Pentium II 233 Mhz, the S-Spec SL264 means it was the first commercial P-II produced. However, this sample is marked "NOT FOR RESALE" and contains a Q-Spec code which indicate it was an engineering or qualification sample. This rare sample is a commercial Pentium-II 233 relabelled as an enginnering sample. It was produced in early september 1997 where the P-II was introduced on May, 7th 1997.
