I officially retired from machine code when they switched from 8-bit to
16-bit. With 8-bit, I could actually memorise then entire 6502
instruction set in my head, by the numbers (eg. 96 = return from
subroutine). With 16-bit, it was just far too complicated for the whole
thing to stick in my head in one go!
Low-level stuff is really interesting, but the problem is these days
everything is built library on top of another (eg. X-Windows, Gnome)
that it is almost impossible to achieve anything in machine code.
