When was the first Donkey Kong arcade game released?

Is it true or urban myth that it was really supposed to be called Monkey Kong but someone messed up in the translation? It would certainly make more sense. Anyone know for sure?

ls the slot machine being compared with the arcade game in the picture?

Tincantitan1, I read the creator tried to translate 'stubborn ape' but it came out 'Donkey Kong'. it was funny enough so they kept it.
