Oral history by Joe Circello, whom was the lead designer of the Motorola 68060 processor. The 68060 was the last of the classic line and the first superscalar 68000 based CISC microprocessor architecture. Some portions of development of the 68060 actually started outside of Motorola -- with Motorola acquiring the team to finish the work. The interview talks about 68060 performance targets, the process of development, technical details, and a bit about the future after the 68060.
Interview starts at ~ 2 minutes in. I hope there's at least one hardware geek (other than me) here who enjoys this
