Abstract
It was a different computing world in the late 1980s. Many if not most researchers in the computer architecture area had become convinced that complex instruction sets such as the Intel x86 were doomed in light of the many advantages promised by reduced instruction set architecture publications. There were many voices within Intel urging upper management to abandon x86 and get started on some alternative. Even engineers who had worked on Intel's then-flagship 486 were expressing serious reservations about whether the x86 architecture could be “dragged further up the hill” to be, if not directly competitive with emerging RISC designs, at least close enough for x86 to remain profitable.
