What ever happened to Tandem and NonStop OS 1975

Sure. That is the most convenient way to find all the obsolete instructions. The whole point of this is to not have the code have to be executed in kernal mode. You do want...

It appears that you don't know enough about how they actually work in silicon.
Aye, but before the user even gets to ignore Caches and Pipelines the hardware has to be built and purchased by said user. The guys building the hardware *do* care and if they *really* care if they are trying to make a fast affordable chip ship on time.
I was responding to the posts concerning your rather naive buttertion that souped up -11s could compete with workstations. I have provided several technical reasons why that did not happen, and I've also highlighted the evolution of the -11 through to the MicroVAX (although I believe that evolution to be a marketing myth). MicroVAXes weren't quick enough or cheap enough, so DEC resorted to making MIPS based workstations to fill the gap.
Relatively little compared to the VAX-VMS. pee all compared to Itanium, and the Alpha has the Itanium beat hands-down on sales at the current point on the Itanium's life-cycle.
Naw, that is still arse over breast.
At the end of the day you can say what you like. The guys who actually design and make microprocessors for a living have different ideas about the relationship of Architectures, Instruction Sets and Implementations.
