Creating the world's first dual instruction set CPU.
World's first? What about the VIA C3 (or earlier NEC V20)? I'm sure there are more / earlier ones.

That's not the same thing, it's more like a hidden feature than the ISA of an entirely different CPU.
There was also the semi-mythical PowerPC 615 that was meant to have both PowerPC and x86 instruction sets. W
