Original LAI Teenage Mutant Ninja Turtles cost around $7000 NEW. My old man bought THREE, and put them on location. He was called TWO days later because one of the units was not accepting coins. He thought the coin acceptor was jammed. The cashbox was FULL and the machine would not accept any more credits. I'd say the three machines paid for themselves very quickly. He recalls that the only other Video Game that did this was Street Fighter 2. He used to have a row of three of them on one location and there used to be "real" fighting over the machines !

The pinballs were even worse (or better  )
