Actually...
8. Code isn't just 0100110 010101 10100 011
When I first learned about computers and programming we had a PDP-11 at school. If that got turned off, or threw a wobbly (about twice a week) the computerprogramming teacher had to input the first dozen or so lines of assembler code IN BINARY - using up-down switches on the front panel. After that, the machine would start reading paper punch tape.
As you may imagine, he got pretty pissed-off with anyone who flicked the switch!
