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.
