Lately Coos could buy a Bally Bikini in Holland. This bingo had been landed coincidentally with a salesman, who found the machine in a lot of pinballs. It was clear dat this fellow wanted to get rid of it, because it did not function, it was too difficult to handle (he did not know that he could dismantle the head off the cabinet), it was heavy and the frontbar with the buttons was missing. In other words, Coos could take the bingo for a few euro's. Fortunately did I have another frontbar from a Lido. This bar was not identical to the Bikini, but Coos could fix it, with a new plate and new buttons. He started a technical restoration, replaced the electronical register for a original and cleaned everything, so that he could play again. As it was his first OK bingo and so his first Magic Screen, it was nice that the Bikini was not too bad. Of course extra Tilts devices were fitted and a remote system for registering, but Ed advised to cut out all those things rigorously.
When the Bikini was ready, the bingo had to be put into use. A splendid moment for the Dutch hardcore bingo bunch to visit Coos and play his quick growing collection. So Ed, Peter, Frans and Coos played the Double Header, Gayety, Twist, Big Wheel, four different Miss America's and the new Bikini. I had a funny feeling this Bikini was different from the Bikini's I am restoring and suddenly I noticed the difference. The lay-out of the playing card was different. Numbers 24 and 7 were changed position. See the pictures of the changed and original play card. That was the reason why the wiring underneath the Magic Screen unit had been changed. Coos had seen the cut wiring, but everything worked fine, so why looking for the reason?

Being a man of the trade, Ed  knew instantly what has been happened. The Lido and Bikini were mostly played for the OK games, so the players played the balls on the left hand side, where numbers 9 and 25 were for the first OK sector and numbers 1, 19, 24 and 23 for the second sector. So to make it more difficult to get an OK, the manager fitted a new (100% lookalike) playing card, on which number 24 and 7 had changed position. There was a sign plate with "For amusement only", but the management had to earn money.
