There's an MK2 at my local barbershop, has been ever since it came out. I'm guessing the owner bought, most of the time owners of the arcades ask people if they can put their machines in their buildings of establishment.

I have a MK II arcade in my house.

I was at Ocean City, NJ a week ago and found a real cherry MK2 machine, it looked untouched. The joystick and buttons were pretty good, and I got my ass handed to me by the computer, naturally. They also had UMK3 but that had a crapped out screen. And the AI stinks for it anyway. The only fighting game I got to play against a person was MvC2 and the unfortunate slob was much talk, little ability.

One day I was playing Mortal Kombat Deadly Allance then I bought something in the krypt.Then I read it and it said that Mk2 was popular that people would steal the circuit boards(arcade)
