VAX was pretty much the last CISC-y architecture that sold in any sizable units, AFAIK. x86 has been a CISC-y architecture off-chip that gets translated into a RISC-y architecture in-chip for quite some time now. Lots of instructions are in the "slow path" and are provided only for backwards compatibility. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://ComputerGraphicsMuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!
