the slot types are "Pachislo" machines from the Japanese "Pachisuro."
The Pachinkos are just that.
Both are used in pachinko parlors on the Ginza. You can only trade your winnings for "prizes," which the locals then take around the corner and trade for cash.
THOSE LINKS ARE BAD!!!!!!! They are old machines that have been around the corner too many times. Check out http://www.stealthhomeamusement.com/
One of the few Japanese slot dealers out there who actually provides customer service.
People buy the pachislos when they are in a state that doesn't allow slots.
