Ah, yes. I actually remember the first time I learned what each of those options meant. My Dad had purchased an 8088 earlier that year and it was still a mystery to us (though Dad and I were the most proficient). One late evening while my Mom was finishing up something for work using "Word Star", she tried to print something but the printer was not turned on[0].

The issue was quickly solved but the prompt remained on screen. The funny thing about the prompt was that, at the time (I was 8?), I didn't understand that it was asking a question and provided for more than one answer. Every time my Dad had seen the prompt, he hit "A" and redid whatever trivial thing he was doing. I had learned to do the same.

Confidently, and very unhelpfully, I hit "A", watching the past hours work vanish. It was the first time DOS made my mom cry.

[0] Forgive me, it was a while ago; it may have been unplugged or some other trivial issue.
