Ohhhh right. Well its worth the <$1 of input costs.
That would be way more complex to have the motherboard play than a sequence of beeps at different frequencies. Especially at the time.
You could just about play speech using one bit output using pulse-width-modulation. But it was almost unrecognizable. And would take a lot of memory for the time.
It was usual to have different numbers of beeps for POST errors.
But this was an age when a PC would say "Keyboard error. Press any key to continue", so things were not thought out that well.
If your keyboard was actually working, you pressed a key. If it was not working, you went to get new keyboard. What is "not thought through" about that?
But you're not allowed to proceed in life until you've pressed any key!
