IBM, Apple, RISC, and the Roots of the Power Mac
To coincide with our latest gallery addition, a 1994 "Introducing Power Macintosh" Ad, we recommend this interesting new article at Low End Mac by the talented Tom Hormby.
It begins:
"The story of the PowerPC began in the early seventies when John Cocke and his team at IBM began designing one of the earliest RISC processors, the 801. By the mid-seventies, it was believed that microprocessors had become as complex and feature rich as they ever would, so further advances would have to come in the form of miniaturization or fundamental shifts in thinking about processor design."
