x64 Assembly and C++ Tutorial 3: Intro to Registers, 8086 Register Set

In this third tutorial, I’d like to introduce the register set by explaining where it’s come from. The 8086 is the grandpa of our x64 CPU’s. We still have most of the registers from the humble 1970’s 8086 so I’ll weave my way to the x64 register set via the 8086 (in this tutorial), then the 386/486 register sets (in the following tutorial) and finally we’ll get to how the modern register looks. The Registers are strange, impossibly flexible and typeless entities residing on the CPU. They are the fastest me
