I recently went back to practicing on my msx machines programming z80 assembly. More precise; when I wrote a lot of msx software in the 80s, I typed in hex opcodes directly without knowing the mnemonics. I still remember that it is a little rusty; it is fun to do still. You don’t need to remember much and because the computer (z80, graphics chip, sound etc) will never change, I find it quite refreshing to do.
