Well, the original C was pretty much exactly how a PDP-11 worked. And the PDP-11 was a source of design inspiration for the original Intel x86 and Motorola 68000 chips. So there were computer chips sold in the 1970s that worked a lot like C thinks. You are right that there were also ones that didn't. Going forward from close to 1980 you added more and more features to all architectures that diverge.
