> Can anyone speak on how it is to move from an older assembly, to a modern CPU? The modern CPU with orthogonal instruction set is just as easy (possibly easier because you have more and larger registers, making it easier to get ‘real’ results) until you start to look at performance. Then, you hit the problem of having to understand how your target CPU does out-of-order execution, how large its caches are, how they are organized, etc. Modern CPUs out there that have very little of that exist, though.
