I was discussing arcade games with my sister and we both started singing
the Donkey Kong tune. At the very same off-beat moment we interupted
the tune with a "youyou" sound, and we sure that was the very moment
you needed to jump over the first barrel on the first level. Amazing how
you remember these games after 20 years.

But if I ever need to rescue a lady from an ape, I, for one, know when
to jump over the barrels he'll be trowing at me. I can hear the Animal
Planet voice over go: "This playing may seem a waste of time to the
untrained eye, but the human puppy learns the most important life
lessons this way, like flying spacecrafts and jumping over barrels.

I never realized those games were analogue. But come to think
of it, I was very disappointed at first with the Atari 800XL sound.
Later on, I started programming the box, using the "distortion"
parameter mostly. Only after 15 years I recognized what it must
have been: pulse width modulation, not distortion.

Ps. What was the game with the camels, that used this sound for the
rocket motor? It was the only game I know that was flown from
right to left. Probably referring to arabic writing direction.
