Actually, when you've had to hand code machine code, it's not too hard to 
memorise the opcodes (the hex codes). In the last week or so, I was put in 
the position of having to dis-assemble some 6800 code, and I successfully 
did that for over two pages of code. I haven't used 6800 code since the 
*very* early 80's.

The computer I hand coded for was the DREAM 6800.
