Released one year after the Pentium 60 & 66, the new revisions come with another socket (Socket 5 instead of Socket 4) and more Mhz. The Pentium Processor clocked at 90 and 100 Mhz were announced on 7th March 1994. The first version had the famous FDIV bug. This sample was produced in early February, one month before the official launch. However, mass availability wasn't real before mid-94.
