Intel introduced the 8086 microprocessor in 1978 and it still has a huge influence through the modern x86 architecture used today. This 16-bit processor contains a bunch of registers, some of them hidden. I reverse-engineered the 5-bit code that it uses to select registers. 🧵

The Intel 8086 processor (1978) has a complex instruction set with instructions from 1 to 6 bytes long. How does the processor determine the instruction length? It turns out that there is no explicit length. A ROM says if 1 or 2 bytes, then microcode fetches bytes until done. 🧵
