I started by reading disassembled real-mode x86 code. Not bad, not great. The thing that took me the longest to “get” was how much was implicitly coded into each instruction. Once I figured out how the accumulator worked, plus the way the flags influenced jump instructions, I found over time that most other architectures are more similar than they are different.
