That's 10 people! 10. Not only the number '2' in binary (base 2), but the function key labelled as 'BREAK' on the Acorn BBC Micro which did a soft reset.

At school, we would re-program the break key to recover the previous program in memory, and re-run it. Like this:

*key10 OLD||M RUN||M

What did you do with the break key?
